The wife of one’s son. Scriptural parent-in-law/daughter-in-law pairs include Terah/Sarai (Gen. 11:31), Judah/Tamar (Gen. 38:11, 16, 24; 1 Chron. 2:4), Naomi/Ruth (Ruth 1:6, 7, 8, 22; 2:20; 4:15), Naomi/Orpah (Ruth 1:6, 7, 8), and Eli/wife of Phineas (1 Sam. 4:19).

The OT is forceful in governing the conduct of fathers-in-law toward their daughters-in-law, proscribing any sexual behavior between them (Lev. 18:15; 20:12; Ezek. 22:11). The narrative drama of efforts by the widowed daughter-in-law Tamar to conceive by her father-in-law, Judah, turns on this point, since he had deprived her of her levirate marriage rights (Gen. 38:6–27).

Otherwise, the biblical expectation is that a daughter-in-law will have a close filial relationship with her parents-in-law. Naomi calls her daughters-in-law “my daughters” (Ruth 1:11, 12, 13), and Ruth’s oath to her is frequently adopted by couples in modern marriage ceremonies (Ruth 1:16–17). In his anger at Israel, God refers to daughters and daughters-in-law similarly (Hos. 4:13–14). Indeed, an image of ungodliness is the rebellion of a daughter-in-law against her mother-in-law (Mic. 7:6; Matt. 10:35; Luke 12:53).

Human Uses and Metaphors

Fire is a basic necessity for various human activities such as cooking (Exod. 12:8; Isa. 44:15–16, 19; John 21:9), warming (Isa. 44:16; Jer. 36:22; John 18:18), lighting (Isa. 50:11), manufacturing (Exod. 32:24), and refining metals (Num. 31:22–23). Fire is also an important means of maintaining the purity of God’s people, used to punish sinners (the sexually immoral [Lev. 20:14; 21:9; cf. Gen. 38:24] and the disobedient [Josh. 7:25; cf. 2 Kings 23:16]) and to destroy idols (Exod. 32:20; Deut. 7:5, 25; 2 Kings 10:26), chariots (Josh. 11:6, 9), and the cities of Canaan (Josh. 6:24; 8:19; 11:11; Judg. 18:27). As an essential means of worship, fire is used to burn sacrificial animals (Gen. 8:20; Exod. 29:18; Lev. 1:9; 3:3; 9:10, 13–14, 20) and grain offerings (Lev. 2:2, 9; 9:17).

The Mosaic law has several regulations concerning fire. Regarded as work, starting a fire is forbidden on the Sabbath (Exod. 35:3). It is the responsibility of the priests to keep the fire burning on the altar (Lev. 6:9, 12–13). The use of an “unauthorized fire” for sacrifice is forbidden (note Nadab and Abihu’s death [Lev. 10:1–2; cf. Num. 3:4; 26:61; 1 Chron. 24:2]). Also, contrary to the Canaanite religious custom, burning children is forbidden (Deut. 18:10), though the Israelites failed to keep this command and elicited God’s judgment (2 Kings 16:3; 17:17; 21:6; Jer. 7:31; 32:35; note Josiah’s ban in 2 Kings 23:10).

As a metaphor, fire also signifies human anger (Ps. 39:3), wickedness (Isa. 9:18), self-reliance (Isa. 50:11), evil planning (Hos. 7:6–7), lust (Prov. 6:27–28), evil speech or tongue (Prov. 16:27; James 3:5–6), and, paradoxically, kindness to an enemy (Prov. 25:22; Rom. 12:20).

Divine Uses and Metaphors

In the Bible, God is described as the ruler of fire (Ps. 104:4; cf. 1 Kings 18). Positively, God sends fire to signify his acceptance of worship (Lev. 9:24; Judg. 13:19–20; 1 Kings 18:38; 2 Chron. 7:1–3; cf. Luke 9:54). God also purifies his people by fire in order to provide them with abundance (Ps. 66:12), to cleanse them of their sins (Isa. 6:6–7), to refine them into the true remnant (Zech. 13:9), to restore true worship (Mal. 3:2–3), to bring forth genuine faith (1 Cor. 3:13, 15; 1 Pet. 1:7), and to give Christians a true joy of participating in Christ’s suffering (1 Pet. 4:12). God also promises to make his people like a firepot and a flaming torch that will burn the surrounding enemies (Zech. 12:6). Negatively, God uses fire to punish the wicked and disobedient (Gen. 19:24; Exod. 9:23; Num. 11:1; 16:35; 2 Kings 1:10, 12; Isa. 29:6; 34:9–10; 66:24; Ezek. 38:22; 39:6; Rev. 20:9). God is a farmer burning unfruitful trees (John 15:2, 6; cf. Matt. 3:10; 7:19; 13:40) and “thorns and briers” (Isa. 10:17). The eternal fire of hell is the place where God’s final judgment will be executed (Matt. 5:22; 25:41; Mark 9:45–49; Jude 1:7; note the “lake of fire” in Rev. 20:14–15; cf. 14:10; 21:8).

Fire is also a symbol used to image the indescribable God. It symbolizes God’s presence: a smoking firepot with a flaming torch (Gen. 15:17), the burning bush (Exod. 3:2; cf. Elijah’s expectation [1 Kings 19:12]), the pillars of fire and smoke (Exod. 13:21–22; Num. 14:14), the smoke on Mount Sinai and in the tabernacle and the temple (Exod. 19:19; Num. 9:15–16; Deut. 4:11–12; Isa. 6:4). Fire marks God’s protection: the “horses and chariots of fire” (2 Kings 6:17; cf. 2:11), the “wall of fire” (Zech. 2:5). Fire also represents God’s glory: God’s throne (Dan. 7:9; cf. Ezek. 1:4, 13; 10:2, 6–7), God’s form (Ezek. 1:27), the seven spirits of God before the throne (Rev. 4:5). God in his holy wrath is also likened to a burning fire (Pss. 79:5; 89:46; Isa. 5:24; 33:14; Jer. 15:14; Ezek. 21:31; 22:21; Hos. 8:5; note the expression “consuming fire” [Deut. 4:24; Isa. 33:14; Heb. 12:29]) and even to a fiery monster (Ps. 18:8; Isa. 30:33; 65:5; cf. Job 41:19–21). Fire is an important element in the description of the day of the Lord (Joel 2:3; cf. 2 Pet. 3:12). God’s words in the prophet’s mouth are likened to a fire (Jer. 5:14; 20:9; 23:29).

Fire is also used to speak of Jesus. John the Baptist refers to Jesus’ baptism as one with the Holy Spirit and fire (Matt. 3:11). Jesus identifies the purpose of his coming as casting fire on earth (Luke 12:49). The returning Jesus is portrayed as coming in “blazing fire” (2 Thess. 1:7), and the eyes of the glorified Christ are likened to “blazing fire” (Rev. 1:14; 2:18; cf. “flaming torches” in Dan. 10:6). In Acts 2:3 the Holy Spirit is portrayed as the “tongues of fire.”

The mother of an individual’s spouse. Isaac married Rebekah, Milkah’s daughter. Milkah is thus Isaac’s mother-in-law (Gen. 24:47). The most well-known biblical example is Naomi, Ruth’s mother-in-law (Ruth 1:3–4). Jesus healed Peter’s mother-in-law of a fever (Luke 4:38–39). The law forbade a man to have sexual intercourse with his mother-in-law (Deut. 27:23). Social chaos was often described as a breakdown of family relationships, including that between daughter-in-law and mother-in-law (Mic. 7:6; Luke 12:53).

Bathing was built into the very structure of the culture of the biblical world. Jewish ritual baths, miqwa’ot, were found throughout the Mediterranean world in both private homes and public places. Likewise, bathhouses were common in the Greco-Roman landscape of urban life. Ancient literary and archaeological sources attest to the traditions of curative bathing throughout the Mediterranean basin.

Homer wrote of bathing in warm water as a luxury and part of a hero’s welcome. Greek philosophers describe taking a hot bath as reserved for the aristocracy. In contrast, the Spartans bathed only in cold water. The Greeks incorporated full bathing facilities into their gymnasium programs. It was customary in the Roman Empire for men and women to bathe separately. Some of Rome’s extant public baths have inscriptions indicating separate spaces for the sexes. Some of the emperors, however, tolerated mixed bathing.

In the OT, bathing is often part of purification rituals. The Israelites had cleansing rituals that included bathing in running water (Lev. 15:13). In the NT, washing or bathing (baptizing) can be either literal or metaphorical (Luke 12:50; Rom. 6:3–4; 1 Cor. 10:2; 12:13; Col. 2:12; Rev. 7:14; 22:14). Baptizing is presented as a symbol of purification from sin (Acts 22:16) or spiritual pollution, and water baptism became the initiation rite for the early Christian community. Early Jewish Christian communities had a preference for using the Jewish ritual baths or pools for their baptisms because their water was channeled in from natural sources. See also Baptism.

The KJV translation for a young girl, an unmarried woman or virgin, or a female servant. At least five Hebrew words are used to refer to such women. Betulah refers to an unmarried virgin or a young woman who has had no sexual experience (Gen. 24:16; Job 31:1; Exod. 22:16–17). A man who forcefully lay with such a woman was expected to marry her (Deut. 22:13–19). When David was old, a virgin was found to lie at his side to keep him warm (1 Kings 1:2). Israel as a nation is identified as a young virgin (Jer. 31:4). The second term is ’amah, translated “bondwoman,” “maidservant,” “maid,” “bondmaid,” “servant,” or “female servant” (Gen. 20:17; Exod. 2:5). The third is shipkhah, which refers to a female slave who is of close kinship to her master (Gen. 29:24). The fourth is na’arah, which is translated “unmarried girl” (Esther 2:4 [NIV: “young woman”]) or “servant” (Esther 4:4 [NIV: “female attendant”]; Ruth 2:23). The fifth is ’almah, which is translated “girl” (Exod. 2:8), “virgin” (Isa. 7:14), or “maiden” (Prov. 30:19 [NIV: “young woman”]).

In the NT, several Greek words are sometimes translated as “maiden” in the KJV. Parthenos refers to a “virgin,” male or female (Matt. 1:23; Acts 21:9; Rev. 14:4). Pais generally means “a young girl,” “maiden,” or “child” (Luke 8:51, 54). Paidiskē refers to a “female slave,” “servant maid,” or “servant girl” (Mark 14:66; Luke 12:45). The word korasion refers to a “girl” or “little girl” (Matt. 9:24–25). Nymphē refers to a “young wife” or “bride” (Luke 12:53; Rev. 21:2).

When God creates humans, he pronounces them “very good/beautiful” (Gen. 1:31). They are designed to be magnificent visual displays of God’s character (1:26–27). Human sexuality originally is set in a context of overwhelming beauty. God’s first command is to reproduce and extend this paradise throughout the earth (1:28). Human sexuality is not simply a mechanism for reproduction. From the outset it has been about completion, without which there is loneliness (2:18).

Although the Bible does not define the distinctives of masculinity and femininity in any detail, it does defend that there are distinctions between the genders. Behaviors that confuse the genders are explicitly condemned (Deut. 22:5; 1 Cor. 6:9; 11:4–16).

Homosexual intercourse (Lev. 18:22; 20:13; Rom. 1:24–27; 1 Cor. 6:9; 1 Tim. 1:10) and intercourse with an animal (Exod. 22:19; Lev. 18:23; 20:15–16; Deut. 27:21) are violations of God’s created order.

Nakedness

“Nakedness” is confined to the genitals and buttocks (Exod. 20:26; Isa. 20:2–4; Ezek. 23:18, 29; Nah. 3:5) and, after the fall, is synonymous with shame (Gen. 3:7–10; 1 Sam. 20:30; Isa. 47:3; Jer. 13:26; Mic. 1:11; Nah. 3:5; Rev. 3:18; cf. Rom. 1:23–24; 1 Cor. 12:23–24). A woman’s breasts are recognized as erotic (Prov. 5:19; Ezek. 23:3, 21) but not shameful. God slaughters an animal in order to cover nakedness (Gen. 3:21). Ultimately, when sin and death are removed and the body raised, the redeemed will have no shame and will be clothed only in their righteousness (Rev. 19:5–9).

Exposing nakedness is an action used to humiliate enemies (2 Sam. 10:4–5; 1 Chron. 10:9; Isa. 47:3). Jesus is stripped naked (Matt. 27:28, 35–36). Violating another’s nakedness includes touching or seeing (Deut. 25:11) and produces extreme personal disgrace (Lev. 18:6–19 NASB; Hab. 2:15–16). It is an act of grace to cover another’s nakedness (Isa. 58:7; Ezek. 18:7, 16). To even talk or laugh about inappropriate exposure brings dishonor (Gen. 9:21–23). The overarching principle is purity (Lev. 18:24).

Marriage and Adultery

Although damaged by sin, marriage continues to be the ultimate human relationship involving intimacy, privacy, and liberty. Marriage is defined by a covenant—a contract witnessed and enforceable, not just a promise made in private. The couple separate from their parents to become “one flesh” (Gen. 2:24).

Once the marriage contract is agreed upon, the couple are married. They cannot consummate the marriage until the economic commitments of the contract have been delivered (Matt. 1:18; 25:1–13). This is celebrated with a feast. Jesus uses this custom as an analogy for his departure and return (John 14:1–3).

Paul commands husbands to love their wives (Eph. 5:25–33; cf. Gen. 24:67; 29:20; 1 Sam. 1:5; Eccles. 9:9; Song 8:6–7). Nowhere in the Bible is a wife commanded to love her husband, though older women should teach younger women to do so (Titus 2:3–4). Love is the husband’s responsibility. Love is a command that can be obeyed, not just a pleasurable feeling over which one has no control. The model of husbandly love is Jesus laying down his life for his people.

The ecstasy of making love is celebrated in the erotic Song of Songs, which holds out the hope of such marital delight even now. The axiom of marriage is a righteous jealousy (cf. Exod. 20:5; 34:14; Num. 5:14, 30; Prov. 6:34).

The first year of marriage is especially important and is protected by exemption from military service (Deut. 20:7; 24:5).

When a man dies without a male heir, his widow’s possession of that part of the family estate can result in her marrying a man from another family and so alienating that land. This can be resolved either by the injustice of eviction or by the device of levirate marriage. The nearest male relative of the deceased husband marries the widow, and their son then inherits the deceased husband’s name and title to the land (Deut. 25:5–10; cf. Gen. 38; Ruth).

Concubines are wives from poor families, slaves, or captives, and their marriages are protected (Exod. 21:7–9; Deut. 21:11–14).

Rape of a married woman constitutes adultery by the rapist, not the victim. Consensual sex with a married woman is adultery by both parties. Rape of a single woman is treated as fornication, with no blame attached to the woman. Her father has the option of letting her marry the man or receiving significant financial compensation (Exod. 22:16–17; Deut. 22:23–27). Her father has the right to take the money and refuse the marriage. To falsely accuse a woman of adultery is a crime (Deut. 22:13–21).

Prostitution is an extreme form of adultery or fornication and totally forbidden (Lev. 19:29; Deut. 23:17). Under the new covenant, this warning is heightened by the reality of the gift of the Holy Spirit transforming each believer into the temple of the Lord (1 Cor. 6:15–20).

Originally, marriage between siblings is implied (Gen. 4:17, 26; 5:4). Abram married his half sister, Sarai (Gen. 20:12; cf. Gen. 11:29; Num. 26:59). The Mosaic covenant at Sinai bans marriage to blood relationships closer than first cousins and to in-laws (Lev. 18:6–30; cf. 2 Sam. 13; 1 Cor. 5:1).

Polygamy occurs soon after the fall (Gen. 4:19–24). It is never explicitly forbidden in the Bible, but it is managed by OT law so as to restrain further injustice and damage. It is always seen as less than satisfactory (cf. Gen. 29–30; 1 Sam. 1:6; 2 Sam. 13; 1 Kings 1–2; 11). In the NT, monogamy is mandatory for those who would lead the church (1 Tim. 3:2, 12; Titus 1:6). (See also Premarital and Extramarital Sex.)

Self-Control and Purity

The violation of sexual purity is a decision of the heart (Ezek. 23:11; Matt. 5:28). The biblical concept of lust entails more than just physical arousal. It involves a strong desire for/coveting of (cf. James 1:14–15) something that one has no right to acquire. This establishes both the need for self-control (Titus 2:5–6) and the availability of appropriate options (1 Cor. 7:2, 5, 9). Masturbation is nowhere mentioned in the Bible (Gen. 38:9 is about failure to fulfill the levirate). The critical issue is lust.

Sexual misconduct is never the responsibility of the victim (Deut. 22:25). Nevertheless, for reasons of personal safety as well as out of concern for one another, the family of Christ must practice modesty in dress (1 Tim. 2:9) and consider how to build one another up rather than put stumbling blocks in each other’s way.

God always provides the believer with what is necessary to resist temptation and make the right choices (1 Cor. 10:13). Consequently, a significant aspect of every parent’s role is to teach godly sexual wisdom to children before they face such challenges (cf. Prov. 1–9).

The gospel requires us to view sexuality from a wider perspective. Reproduction also occurs through the preaching of the gospel, calling forth new birth and a new people (Matt. 28:18–20). This gospel call will divide families (Luke 12:53). Singleness is no barrier to one’s ability to fulfill the command to multiply and fill the earth (Isa. 56:3–8). In times of distress it may be better to remain single (1 Cor. 7, esp. v. 26). This is also a gift of God (1 Cor. 7:7), given to equip one for the fulfillment of the gospel commission.

When God creates humans, he pronounces them “very good/beautiful” (Gen. 1:31). They are designed to be magnificent visual displays of God’s character (1:26–27). Human sexuality originally is set in a context of overwhelming beauty. God’s first command is to reproduce and extend this paradise throughout the earth (1:28). Human sexuality is not simply a mechanism for reproduction. From the outset it has been about completion, without which there is loneliness (2:18).

Homosexual intercourse (Lev. 18:22; 20:13; Rom. 1:24–27; 1 Cor. 6:9; 1 Tim. 1:10) and intercourse with an animal (Exod. 22:19; Lev. 18:23; 20:15–16; Deut. 27:21) are violations of God’s created order.

Nakedness

“Nakedness” is confined to the genitals and buttocks (Exod. 20:26; Isa. 20:2–4; Ezek. 23:18, 29; Nah. 3:5) and, after the fall, is synonymous with shame (Gen. 3:7–10; 1 Sam. 20:30; Isa. 47:3; Jer. 13:26; Mic. 1:11; Nah. 3:5; Rev. 3:18; cf. Rom. 1:23–24; 1 Cor. 12:23–24). A woman’s breasts are recognized as erotic (Prov. 5:19; Ezek. 23:3, 21) but not shameful. God slaughters an animal in order to cover nakedness (Gen. 3:21). Ultimately, when sin and death are removed and the body raised, the redeemed will have no shame and will be clothed only in their righteousness (Rev. 19:5–9).

Exposing nakedness is an action used to humiliate enemies (2 Sam. 10:4–5; 1 Chron. 10:9; Isa. 47:3). Jesus is stripped naked (Matt. 27:28, 35–36). Violating another’s nakedness includes touching or seeing (Deut. 25:11) and produces extreme personal disgrace (Lev. 18:6–19 NASB; Hab. 2:15–16). It is an act of grace to cover another’s nakedness (Isa. 58:7; Ezek. 18:7, 16). To even talk or laugh about inappropriate exposure brings dishonor (Gen. 9:21–23).

This is celebrated with a feast. Jesus uses this custom as an analogy for his departure and return (John 14:1–3).

Paul commands husbands to love their wives (Eph. 5:25–33; cf. Gen. 24:67; 29:20; 1 Sam. 1:5; Eccles. 9:9; Song 8:6–7). Nowhere in the Bible is a wife commanded to love her husband, though older women should teach younger women to do so (Titus 2:3–4). Love is the husband’s responsibility. Love is a command that can be obeyed, not just a pleasurable feeling over which one has no control. The model of husbandly love is Jesus laying down his life for his people.

Her father has the right to take the money and refuse the marriage. To falsely accuse a woman of adultery is a crime (Deut. 22:13–21).

Prostitution is an extreme form of adultery or fornication and totally forbidden (Lev. 19:29; Deut. 23:17). Under the new covenant, this warning is heightened by the reality of the gift of the Holy Spirit transforming each believer into the temple of the Lord (1 Cor. 6:15–20).

Originally, marriage between siblings is implied (Gen. 4:17, 26; 5:4). Abram married his half sister, Sarai (Gen. 20:12; cf. Gen. 11:29; Num. 26:59). The Mosaic covenant at Sinai bans marriage to blood relationships closer than first cousins and to in-laws (Lev. 18:6–30; cf. 2 Sam. 13; 1 Cor. 5:1).

Polygamy occurs soon after the fall (Gen. 4:19–24). It is never explicitly forbidden in the Bible, but it is managed by OT law so as to restrain further injustice and damage. It is always seen as less than satisfactory (cf. Gen. 29–30; 1 Sam. 1:6; 2 Sam. 13; 1 Kings 1–2; 11). In the NT, monogamy is mandatory for those who would lead the church (1 Tim. 3:2, 12; Titus 1:6). (See also Premarital and Extramarital Sex.)

Self-Control and Purity

The violation of sexual purity is a decision of the heart (Ezek. 23:11; Matt. 5:28). The biblical concept of lust entails more than just physical arousal. It involves a strong desire for/coveting of (cf. James 1:14–15) something that one has no right to acquire. This establishes both the need for self-control (Titus 2:5–6) and the availability of appropriate options (1 Cor. 7:2, 5, 9). Masturbation is nowhere mentioned in the Bible (Gen. 38:9 is about failure to fulfill the levirate). The critical issue is lust.

Sexual misconduct is never the responsibility of the victim (Deut. 22:25). Nevertheless, for reasons of personal safety as well as out of concern for one another, the family of Christ must practice modesty in dress (1 Tim. 2:9) and consider how to build one another up rather than put stumbling blocks in each other’s way.

God always provides the believer with what is necessary to resist temptation and make the right choices (1 Cor. 10:13). Consequently, a significant aspect of every parent’s role is to teach godly sexual wisdom to children before they face such challenges (cf. Prov. 1–9).

The gospel requires us to view sexuality from a wider perspective. Reproduction also occurs through the preaching of the gospel, calling forth new birth and a new people (Matt. 28:18–20). This gospel call will divide families (Luke 12:53). Singleness is no barrier to one’s ability to fulfill the command to multiply and fill the earth (Isa. 56:3–8). In times of distress it may be better to remain single (1 Cor. 7, esp. v. 26). This is also a gift of God (1 Cor. 7:7), given to equip one for the fulfillment of the gospel commission.
