Washed in the blood of Jesus. That’s what our early hymns proclaim. We are washed in the blood of the Lamb, the blood of sacrifice, the blood of salvation, the cleansing blood of the messiah Jesus.
For most of us today that sounds like a rather strange concept. But then, when you think about it, so is partaking of the “body and blood” of Jesus as we celebrate what we know as Holy Communion.
In fact, this was a strange concept in the early church as well! Early Christians were in fact often called out for treacheries such as cannibalism and bodily aberration bordering on the macabre when people in the first century heard these words associated with the Blood of the Christ.
Only when disciples learned the “secrets” of the Christian faith would they understand what it meant to partake of the blood of Christ and to be washed in His blood of sacrifice. In a sense, the early church was kind of like a secret society. You had to enter in by means of a secret sign (usually an ichthys or fish). You had to learn the secrets that Jesus taught. And you learned to comprehend and accept the metaphors that defined this relational, bodily, blood-covenant faith.
In fact, the “blood covenant” is not new. The idea of “cutting a covenant” and shedding blood in the process goes all the way back to Abraham when God cuts a first covenant by means of animals to signify the agreement and the loyalty of relationship between Abraham and his descendants and God (YHWH).
Blood was considered the “life source” of being human. And God is the ultimate life giver. Only God can bestow life, just as only God created a living being out of clay made flesh and blood and inbreathed with the “wind” of God’s Spirit.
Therefore, to signify one’s intimate, blood-brother/blood-sister relationship with God, one needed to “shed” a little blood. A covenant is in essence a sacrificial act. One sacrifices one’s own wants and needs to some extent and one’s own path to instead pledge loyalty to following the One True God. One agrees to be guided by God, protected by God, and guaranteed life by God. In return for God’s promise of life and protection, the covenant holder agrees to ultimate and exclusive loyalty, devotion, obedience, love. It is a “blood pact.”
Now this isn’t really that far fetched is it? Have any of you sworn a “blood pact” with anyone? Anyone pledge a fraternity or sorority? Or another kind of society or group in which you make a “blood pact?” Anyone have a best friend in which you swear “blood brothers?” Or “blood sisters?” It’s a way of leaving behind your biological marker in favor of a new kind of identity: one forged by covenant or agreement. It’s an intimate relationship forged, a kind of “marriage” of sorts created, an unbreakable bond promised through thick and thin. You gain a new identity in relationship to that other person that supercedes any other.
This is the nature of the blood covenant. But it doesn’t end there with Abraham. That blood covenant language will continue with something we call “circumcision.” Each time someone is circumcised, they are essentially carving the “mark” of God right onto their body in pledge of covenant!
And each time in Israel’s history that a blood sacrifice is made, it is for the purpose of renewing that covenant, through cleansing or purging we call repentance and a revitalization of faith so as to guarantee that the covenant remains vital and alive. The animal sacrifice represents our own sacrificial heart. In the ritual, blood would be sprinkled onto the stone altar as a visible sign of covenant agreement.
Not long ago we celebrated Jesus’ resurrection day, just after the Jewish Passover. And every time we celebrate Holy Communion, we continue to celebrate that ritual of Jewish Passover combined with Jesus’ additional sign of His “new covenant” in which He Himself has become the Lamb of sacrifice, assuring us life, protection, a dwelling place in God’s eternal house, and entry into the gates of Eden, the Garden City of God, the Holy Living Tabernacle.
But let’s take a moment and talk again about that ritual of Passover. Because here’s where being “washed in the blood” begins. Here is where for Jesus blood merges with the idea of baptism.
For to be “washed” is an “immersion” experience. In immersion, we are not just sprinkling blood on an altar, not just sacrificing animals on an altar, not just circumcising our body (marking ourselves), but we are immersing ourselves in God, in Jesus, to such an extent that we are entirely and fully changed. We no longer just wear an identity. We change our identity.
Who can tell me the story of Passover? [Give people time to answer.]
What happens in the story? [Allow time to go through the story.]
God promises protection and life to all those pledged in covenant to God. But God requires a “sign,” an act of “sacrificial” immersion, for God is about to bring the people out of Egypt and into a new life, a new place, a land of milk and honey, and a new kind of relationship. The people of God will leave their old life behind and will take on a new identity as “people of God,” people of the promised land. And so, God elicits this pledge through a “blood sacrifice” –an experience in which those willing to take the 40-year journey will give up the gods they grew up with in Egypt, throw off idolatry, turn to YHWH, and pledge obedience and honor. They will sacrifice their old life for the promise of a brand new one, in which they will have life in abundance and the promise of a future dwelling in the “house of the Lord.”
The way they were to do this was to kill a lamb and smear its blood all over the doorposts of their homes. This is not a simple mark, but an entire washing of the doorposts and lintel of the house….so that all within the house will be protected and immersed in covenant with God. They are in a sense “painting themselves in.”
The symbolism is clear. The doorposts and lintel in those days were made of stone. The entire house therefore becomes an altar to God. And the household becomes a “tabernacle” washed in the blood of sacrifice, cleansed from idolatry, and sworn in oath to God.
The house is literally “bathed” in blood. And in this covenant “washing” of the doorposts, life is ensured. And a people is born. This is a birthing. When the people emerge from the house, they enter into a new kind of life. And they will never be the same again.
And God tells the people of Israel…..God will be their own Shepherd, they His sheep. He will be their “Shaddai.”
Shaddai –the Hebrew letters mean “Guardian of the Gates/Doors of Israel.” Just as the “angels of God” have guarded the gates to Eden, preserving the Tree of Life until the day when we will again be allowed entry, God now guards the gates/doors of each Jewish home sworn to God by blood oath, guarding His sheep from harm.
For He is the Shepherd. But He is also the Sheepfold, the Sheep Gate, the Door, and the Way.
When Jesus uses these terms to describe Himself as told through the gospel of John, these are not new terms. They are ancient, beautiful, meaningful descriptions of God. Each time Jesus refers to Himself as the gate, the door, the Shepherd, the lamb, the Way, the Truth, the Life, the tabernacle, He is affirming Himself as Messiah, Son of God, YHWH, the Word/Logos, the “way” to the dwelling place of God and the entryway to the final Gates of Eden and the ultimate Tree of Life.
For Jesus is all of these. And His own blood sacrifice proves it. The spilling of His blood must be affirmed by His followers in a sacrificial moment of repentance in which we too, like the Israelites of Egypt, forgo our former life, and are born again by “water and spirit.” By blood and by fire.
A doorway or a gateway is a crossing over. A river is a crossing over. In the scriptures, we continually have covenants made over water and wells and over altars and rock. These are “covenant” symbols, covenant markers.
When Jesus approaches John the Baptist at the beginning of His ministry, He is not in need of repentance, but He IS leaving His old life behind and beginning His mission as sacrificial representative of God, Messiah and Lamb. From that day onward, each step Jesus takes will be one step closer to the shedding of His blood on the cross for the remission of our sins. And one step closer to becoming the true Gateway into the Holy Kingdom of God.
Jesus’ blood is bound in baptism to His mission as the Gatekeeper, the Shepherd, and the Sheep Gate for all those willing to trust Him and follow Him. Jesus makes it known, when we covenant with Him, we are covenanting with God.
When we are baptized in His name, and baptized by the power of the Holy Spirit, we are washed in His blood, immersed in His Spirit of Truth, protected and guarded by the providence of God, and guaranteed eternal life in God’s heavenly kingdom dwelling place.
In Jesus, our heart is our home, and the gateway to our hearts must be “washed” in the blood of the Lamb, so that we too can cross over into a new and vital life in Him.
The mark of the Messiah is the mark of our mission too, as His disciples and apostles, His loyal followers and proclaimers of His message and identity as Lamb of God, Gateway to God.
We just celebrated the day of Pentecost. But Pentecost now continues as we revel and cleanse ourselves in our Holy Spirit baptism, as we wash ourselves in the blood of Jesus, as we not only take on the sign of the Messiah but fully immerse ourselves in His body and blood, communing with Him relationally and spiritually. In Him, we have a new Name, a new identity from which we emerge as proclaimers and life-givers, healers and change agents.
For the Holy Spirit is a spirit of blood, wind, and fire. And we are His fiery prophets.
Today, I call each of you to new life in Jesus, to remember your baptism by water, and to receive in Him your baptism by fire. I ask you now in silent prayer to give your heart truly and fully to Jesus, to allow Him to wash you in the blood of sacrifice. Let us repent of our old life, and be willing to take on the new. For He is the Gate. He is the Door. He is the Way.
He IS Shaddai.

We are protected dwelling in the shadow of Shaddai (Psalm 91:1-7,10). Shaddai in its ancient root means field or land or as derived from Akkadian, mountain. But as a name for God it means the power of the Name, strong, powerful protector, strong one, strength giver, sovereign almighty one. Shaddai can be seen also as the strong Shepherd (hence the reference to field) who keeps the flock together and keeps out the solves or the dogs, the thieves or the robbers, and protects the sheep in the sheepfold). Through the sacrificial love of the Shepherd whose sheep know His Name, the sheep gain both protection and life “insurance.”

Therefore, Jesus said again, “Very truly I tell you, I am the gate for the sheep. All who have come before me are thieves and robbers, but the sheep have not listened to them. I am the gate; whoever enters through me will be saved. They will come in and go out and find pasture. The thief comes only to steal and kill and destroy; I have come that they may have life and have it to the full.
“I am the good shepherd. The good shepherd lays down his life for the sheep. The hired hand is not the shepherd and does not own the sheep. So when he sees the wolf coming, he abandons the sheep and runs away. Then the wolf attacks the flock and scatters it. The man runs away because he is a hired hand and cares nothing for the sheep.
“I am the good shepherd; I know my sheep and my sheep know me—just as the Father knows me and I know the Father—and I lay down my life for the sheep. I have other sheep that are not of this sheep pen. I must bring them also. They too will listen to my voice, and there shall be one flock and one shepherd. The reason my Father loves me is that I lay down my life—only to take it up again. No one takes it from me, but I lay it down of my own accord. I have authority to lay it down and authority to take it up again. This command I received from my Father.” (John 10:7-18)
We usually think of the mezuzah as a common and contemporary kind of Jewish iconography. In current day Judaism, the mezuzah is a ceramic, wooden, or leather rectangular box-like container into which a small rolled scroll is placed containing one or two verses from the Torah, typically the Shema from Deuteronomy 6:4-9 or Deuteronomy 11:13-21. The mezuzah is to be affixed to the right-hand door post of the home, or in some cases on the right-hand doorframe of every primary room in the home and slanted toward the entryway. On the outside of the scroll often would be written the words “Shaddai,” in Hebrew, the letters shin, dalet and yud. The three letters are said to mean in acronym: “Guardians of the gates/doors of Israel.”[1] The idea is that God (Shaddai) the mighty One will guard the household and everyone in it from harm through God’s “Word” or covenant promise for those who faithfully enter into that covenant and uphold it.[2]
Already in Jesus’ day, mezuzot or mezuzoth were associated with the container and the Word or Torah portion (called the klaf), inserted into leather pouches and hung in gateways and doorways as a covenant sign of a Jewish household. It is quite likely that Jesus had one on the door of his own home.[3]
In early times however the word mezuzah simply meant “doorpost” or “door,” “gatepost” or “gate.”[4] The mezuzah was the gateway or doorway itself. It could also mean “dwelling place.” This meaning would still have been etymologically vibrant for Jesus and his contemporaries.
To “wait at the door” or “wait at the gate” could mean to “sit at the feet” of someone as a disciple: “blessedness belongs to the one who waits at Wisdom’s doorpost (mezuzah), eager for instruction” (Proverbs 8:34).
The mezuzah was also where a servant who wanted to serve his master for life would have his ear pierced.[5] Even though that servant may have been released, he or she could pledge lifelong service. The piercing of the ear not only sheds blood on the mezuzah (doorframe) but is a covenant marker, a pledge, to the one whose house he or she serves.
As a “dwelling place,” the “house” of the Lord also takes on this connotation. The gateway or doorway (note the similar metaphor in the story of Judah and Tamar, in which she meets him disguised at the gateway) is a transition place. Transition places are always covenant markers in the Hebrew scriptures. Gateways and doorways surround not only homes but cities and gardens, and also sheepfolds and vineyards. They are usually made from stone (not wood as we are accustomed to seeing doorframes), and in this sense mimic “altars.”
To sprinkle “blood on the altar” was to pledge to serve God, who in covenant watched over Israel as Israel’s Shepherd. Likewise, the idea of the mezuzah is a two-way covenant. In return for Israel’s pledge to love and serve only God, God’s “Word” will guard and watch over that household, and that person, who matter where they go (as in Jacob’s dream).
God’s act as “watcher over the gates of Israel” erupts from God’s love and covenant, not from some magical power of the mezuzah itself. Just as the altar has not the power (as in Elijah’s story of God’s power in extinguishing and evaporating the water altar of Baal, and then lighting it up), the mezuzah (whether defined as the door/gate or its symbolic later “box of sh’ma”) is a metaphor for God’s powerful blood-bound covenant, first made with Abraham, then tattooed upon the body through the act of circumcision.
Circumcision is a “cutting of covenant” in which the gateway to the heart and the tool of “fruitfulness” is dedicated only to God. What comes out and goes in through that “gateway” is tethered with God’s “Word.”
This same blood covenant is inherent in the ruins of Jericho, which acted as a mezuzah (memory of sacrificial bloodshed) to the doorway of the Promised Land, the sanctified “residence” of God’s people.[6] Whether land, city, gate, garden, or household, the mezuzah is a passage and a way of passage for those pledging loyalty and fealty to God (in the case of Eden, the gateway was guarded by the mezuzah [Word] and later opened through Jesus [the doorway/gateway].) In return, God bestows upon the covenant keeper divine protection, but also “life.”
“Behold He that guards Israel neither slumbers nor sleeps.” (Ps 121:4)
God as the “protector of life” and the “giver of life” is inherent in the metaphor of the mezuzah. While some later, especially those associated with kabbalah, the spiritual arm of Judaism, moved toward the mezuzah as protection against agents of evil confronted by the Name of God, earlier sages reach back to the Abraham story, in which Abraham barters with God for the salvation of Sodom and Gomorrah, should there be even one “righteous person.” That “righteousness” would be inherent in the metaphor of the mezuzah, as the sages of the Talmud teach that “no city containing even a single mezuzah (sanctified residence) can be condemned.” The mezuzah insured protection of life.[7]
The mezuzah would have signified that if within the walls of even one home of Sodom and Gomorrah there would be a righteous person (meaning one God worshiper, one Jewish household), the cities would be saved. God in fact did vow to spare the cities if even one were found. This drives home the fact that the cities were identified as wholly idolatrous. For God will always protect God’s people from destruction. For this reason, Lot and his family were saved and removed from the city gates, which name engraved on its walls indicated an idolatrous “residence” or “temple.”
The mezuzah as “saving vehicle” is therefore an old one combined with the idea of the stone doorpost/gatepost and altar. In the Aramaic Targum, “…Onkelos explained that a mortal king has servants standing outside his house on guard. [Yet] the King of kings is Himself guarding His servants outside their homes” in the metaphor of the mezuzah.[8] This idea of both the servanthood of God and the idea of the shepherd king will reintroduce itself both in the kingship of David and in the messiahship of Jesus.
Jesus’ identity as the Shepherd of Israel, the Paschal Lamb/Sheep, the Door, the Gate to the Sheepfold, the Word/the Torah and the Servant of all (note the disciples’ foot washing) identifies Him as the same God, who “watches over the gates/doorways” of Israel. His bloodshed will be the ultimate in sacrificial servanthood and fierce covenant love, that which keeps out death, destruction, and evil from those committed to God, and that offers the insurance of “life”!
The word “mezuzah” appears for the first time in Exodus: “And they shall take of the blood and they shall put it on the two mezuzoth (doorposts) and on the lintel (mashkof)…and He will not allow the destroyer to come unto your houses and smite you.” (Exodus 12:7,23)[9]
The Passover, as this passage in Exodus is called, is remembered as Israel’s people “bought with a price.” The idea of blood and deliverance in the Passover ritual, assures people that they will be protected by Shaddai. They are to “stay inside their homes” after eating the Lamb and smearing its blood on the mezuzoth and the lintel (mashkof). That home would then be guarded by God from the smiting of the destroyer (angel of death). Through God’s “Word/Torah” (shekhinah), that is, God’s powerful presence through covenant, life would be ensured, not only on that night, but going forward from that place and into the Promised Land. The power of the mezuzah would ensure that God’s “house” is not just one place, but the metaphor of that one place would serve as a “movable tabernacle” thereafter in every place.
This same promise is seen in the story of Rahab and Joshua in the conquest of Jericho (the gateway to the Promised Land). Rahab’s house was built into the wall of the city. In this she served as a “gateway” herself for the idolatrous city to become a city of promise and life, a city of God when Israel entered in. She gave her word to the Word and posted her own “mezuzah” symbol –a red cord or tikva (an uncommon color…and so very significant) in the stone frame of the city wall/window. This sacrificial “blood on the altar” act ensured her life and the life of her family. Rahab would later marry Salmon and bear Boaz, husband of Ruth, forebear of David, and Messiah Jesus.[10] In fact the word “tikva” (red cord) means lifeline, hope, expectation in Hebrew. Just as in the original Passover story in the Exodus of Israel, that same lifeline is inherent in the mezuzah of Jericho.[11]
The sacrificial overtones of the blood on the mezuzah (doorposts/altar) mark a kind of circumcision of the heart and a sign of repentance on the part of Israel, whose time in Egypt was spent in idolatrous service to Egypt’s gods. Their sign on the mezuzah is a declaration of loyalty to Shaddai and a sacrificing of old beliefs.[12] Yair Barkai also notes that the blood over the mezuzoth and lintel (mashkof) form the Hebrew letter het, signifying that this is also a sign of life (hayyim). In this the doorposts are witnesses. Just as the servant pierces an ear in loyalty to the master, here Israel shows service to God in a testimony written on “stone.”
In kabbalah, the numerical value (gematria) of the word “mezuzah” reveals the word “alive.” This testimony to life is witnessed by the Word of God in the metaphor of the mezuzah. The clinching of the covenant by the words of the sh’ma drive this home. It is not just a written but an oral declaration.
The Shema is named for the first word of the commandment, which is “hear!” Or in our language, “Listen!”
Hear, O Israel: The Lord our God, the Lord is one. Love the Lord your God with all your heart and with all your soul and with all your strength. These commandments that I give you today are to be on your hearts. Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up. Tie them as symbols on your hands and bind them on your foreheads. Write them on the doorframes of your houses and on your gates. (Deuteronomy 6:4-9)
The latter part of Deuteronomy is also sometimes used:
Fix these words of mine in your hearts and minds; tie them as symbols on your hands and bind them on your foreheads. Teach them to your children, talking about them when you sit at home and when you walk along the road, when you lie down and when you get up. Write them on the doorframes of your houses and on your gates, so that your days and the days of your children may be many in the land the Lord swore to give your ancestors, as many as the days that the heavens are above the earth. (Deuteronomy 11:18-21)[13]
The Shema is later quoted by Jesus in answer to the question, “Which is the greatest commandment?”[14] But more importantly, Jesus takes upon Himself in His own identity the various meanings in the metaphor of the mezuzah. This is seen most vividly in the gospel of John, in which Jesus gives Himself many Names, including the Door, The Gate to the Sheepfold, the Word, the Lamb of God, the Way (or entryway) and the Life.
“I am the door of the sheep.” (John 10:7)
In John 10, the mezuzah is the gate/door of the sheepfold. As the messiah of David, the Shepherd of Israel, Jesus takes on the identity of Shaddai, the protector and guardian of the fold. Through His sacrificial blood-covenant, Jesus establishes Himself as protector and life-giver.
“I am the good Shepherd, the good shepherd lays down His life for the sheep.”
Jesus is both way/door/gate and Word, the very presence of Shaddai and the incarnation of the Sh’ma. He is the entryway witnessed and identified through the Word.
In Jesus’ time, a sheepfold is a secure, walled stone enclosures in which sheep are penned when not out to pasture in care of the shepherd. If no secure gate or door is available, the shepherd Himself would guard the entrance at night by sleeping across it/laying Himself across it. This sign of sacrificial presence is a powerful reminder of both Shaddai and God’s Exodus promise:
“None of you is to go out the door of his house until morning.” (Exodus 12:21-22)
The mark of mezuzah is the mark of messiah. And the very stones cry out in His witness![15] Jesus is God’s covenant promise, the blood on the altar, the blood on the Torah. He is the Way, and no one may enter except by Him. For He is Shaddai.
