Old Testament

Students of biblical history must work with several overlapping systems of chronology. This section defines several approaches and describes how they are interconnected.

Absolute and relative dates. Absolute dates consist of a numerical value falling in one of two eras, BC (“Before Christ”; also referred to as BCE, “Before the Common Era”) or AD (Anno Domini, “in the year of our Lord”; also referred to as CE, “Common Era”). For example, Samaria fell to the Assyrians in 722 BC. This system of absolute dating, a commonplace of modern life, was devised only in the sixth century AD, so it is unknown in biblical and other ancient sources. Instead of absolute dates, the Bible and other ancient historiographic sources give relative dates; that is, events are dated in relation to other recorded events, as in 1 Kings 15:1: “In the eighteenth year of the reign of Jeroboam son of Nebat, Abijah became king of Judah.” The system of relative dates in the OT can be collated to form a single relative chronology.

Using royal histories. For the purposes of constructing a unified chronology, the royal history in Samuel-Kings and Chronicles is of central importance, with its tabulations of the ages of the kings at accession and the lengths of their reigns. The biblical chronology can then be assigned to absolute dates by establishing synchronisms with other historical chronicles (most usefully, from Mesopotamia), which in turn can be fixed to a handful of absolute dates. Of particular importance are records (all nonbiblical cuneiform texts) of observed astronomical phenomena, the appearance of which in history can now be calculated with a high degree of mathematical certainty. Annalistic sources (documents that record an entry for each passing year, such as the cuneiform eponym chronicles) are particularly valuable. The Bible contains no annalistic sources, but rather is made up of chronistic sources—that is, texts that record and quantify the passage of time, but without a separate accounting of each year. When miscalculations or textual corruptions affect chronistic records, they are difficult to correct (see 1 Sam. 13:1). The biblical data, consisting of summary figures, probably go back to annalistic sources that were compiled from year to year (perhaps the records mentioned in, e.g., 1 Kings 11:41; 14:19).

The assembly of a unified biblical chronology on the basis of the royal histories is further complicated by the fact that several calendars—royal, agricultural, cultic—were in simultaneous use. There may also have been a discrepancy between Israel and Judah with regard to the reckoning of the cultic New Year. Added to this, in several cases the biblical data imply a period of coregency, during which the reigns of the outgoing king and his appointed successor overlapped, creating the potential for the years of the coregency to be counted twice. In biblical times there were two systems of reckoning dates based on royal succession: the “accession-year” system, which omitted from the length of a king’s reign any partial year from his accession to the first New Year, and the “nonaccession-year” system, which began counting the years of a king’s reign as soon as he acceded. In nonaccession-year dating, any year in which there are two kings gets counted twice: once as the last year of the former king, and once as the first year of the new king. The biblical chronologies appear to use both systems, with a movement from the nonaccession-year system to the accession-year system in later centuries. Obviously, the choice of systems dictates the significance of the figures presented in the Bible and must be taken into account in the collation of data.

Combining royal regnal data and various genealogical tables (based on, e.g., Gen. 5; 11; the summary figures in Exod. 12:41; 1 Kings 6:1), it is possible to reconstruct a putative world chronology from the creation of Adam to the exile. Famously, in 1650 James Ussher followed this procedure, working backward from absolute dates known from classical sources, to determine that the world was created on the night before October 23, 4004 BC. In its day, this was a work of impressive scholarship, but Ussher’s chronology is too short to encompass not only archaeological findings (from the land of Israel itself, there are Neolithic and Chalcolithic artifacts going back ten thousand years), but also findings in all branches of the sciences that corroborate the age of the earth at about 4.5 billion years and the appearance of modern humans approximately two hundred thousand years before the present. Beginning in the first millennium BC, however, the Bible provides chronological data that, with modest adjustments, agree with other historical and archaeological findings.

Weighing the sources. Because of the variety of materials in the OT, it is crucial to determine which sources are of historical value, weighing each in terms of internal and external coherence. As noted above, the backbone of OT chronology is the series of regnal data for the kings of Israel and Judah found in Samuel-Kings and Chronicles. These data are useful because they provide a continuous chronology of several hundred years that can be anchored at several points to datable events in external historical sources. In addition, the history of the kings of Judah and Israel contains references to historical figures known from extrabiblical records. In contrast, the chronology of the OT prior to the period of judges, while internally coherent, cannot be correlated to known absolute dates. Where non-Israelite figures are mentioned, they are often unnamed (e.g., the pharaohs of the eras of Abraham and Moses), anachronistically described (e.g., Abraham’s contacts with the Philistines [Gen. 21:34], a group that did not appear in Palestine until long after the ostensible Middle Bronze Age date of Abraham), or do not correspond to known historical figures (e.g., Abimelek, Nimrod). Although cultural-historical investigation may shed light on the patriarchal narratives and their historical setting, such an approach yields nothing more than vague chronological findings. In some cases, the late date of the biblical texts has obscured chronological indicators, interfering with the project of cultural history. Setting aside questions of the historicity of the patriarchal narratives, apart from the reports of their ages, there is little data to work with when it comes to constructing a chronology of the patriarchs.

The story of the exodus from Egypt presents an event that, in principle, should be datable on the basis of external data. The mass migration of millions of persons, the destruction of the army of a geopolitical superpower, and the subsequent conquest of a small but powerful country are events that promise to provide a chronological anchor for the beginning of Israel’s history. Unfortunately, the event recorded in the Bible has not left a clear mark, either in the historiography of Egypt or in the archaeology of Palestine. On closer inspection, the biblical text contains a number of features that frustrate any attempt to date the events on their basis. Unlike in the histories of the biblical monarchs, the pharaoh of the Exodus, a figure of international stature in his own day, is never named in the Bible. Some have attempted to fix a date to the exodus on the basis of the occurrence of the name “Rameses” in Exod. 1:11; 12:37. This name was not current in Egypt before the thirteenth century BC. If it provides a clue as to the date of the exodus, it does so only at the expense of broader biblical chronology, according to which the exodus occurred in the fifteenth century BC (in particular, based on the figures given in Exod. 12:41; 1 Kings 6:1). It is not until we get into the monarchic period, when the history of Israel is intertwined with that of named international figures, that absolute dates can be established with certainty.

Biblical events that can be assigned absolute dates based on cuneiform historical records include the following. Ahab was king of Israel at the time of the battle of Qarqar in 853 BC. The Kurkh monolith of Shalmaneser III records his participation in the coalition of Hadadezer, though the event is not mentioned in the Bible. Jehu was on the throne of Judah in 841 BC, when Shalmaneser III recorded that he gave tribute to Assyria. Joash was king of Israel in 796 BC, when he rendered tribute to Adad-nirari III. Menahem was king in 740 and 738 BC (see 2 Kings 15:19), when he paid tribute to Tiglath-pileser III (the biblical Pul). Ahaz paid tribute to Tiglath-pileser in 734 BC, and Manasseh to Esarhaddon around 674 BC. These synchronisms provide in each case upper and lower limits for fixing the reign of the kings of Israel and Judah. In some cases, the chronology of the book of Kings must be adjusted to fit these dates, on the assumption that the Deuteronomistic Historian lacked firsthand knowledge about the history of the northern kingdom, was attempting to work with conflicting sources, or made errors in calculation. Other important synchronisms include Hoshea’s coup against Pekah (2 Kings 15:30), dated based on an inscription of Tiglath-pileser III to 732 BC; the fall of Samaria (2 Kings 17:6), dated based on the Babylonian Chronicle to 722 BC; Sennacherib’s Judean campaign in 701 BC (2 Kings 18:13–19:36); the Battle of Carchemish in 605 BC (Jer. 46:2); the capture of Jerusalem in 597 BC (2 Kings 24:12); and the release of Jehoiachin from captivity in 561 BC, coinciding with the accession of Amel-Marduk (2 Kings 25:27).

Periodization of history. In addition to relative and absolute chronologies, biblical scholars refer to several schemes of periodization defined by technological and political developments.

The most ancient scheme of periodization is implied in the Bible itself, which conceives of periods of judges (Judg. 17:6), united monarchy, divided monarchy, and exile. The transitions between phases in this scheme are defined by dramatic social and political discontinuities. Another approach to the periodization of Israelite history involves defining the major transitions in terms of the material culture. Prior to the fall of Jerusalem, modern biblical scholars and archaeologists divide Syro-Palestinian history into several periods, named for developments in metallurgical technology. While there is some variety of opinion among scholars regarding the exact dates used, the following scheme is widely used (given with rough correlations to the biblical periods):

Early Bronze Age – 3300 to 2200 BC (Primeval period?)

Middle Bronze Age – 2200 to 1550 BC (Patriarch)

Late Bronze Age – 1550 to 1200 BC (Period in Egypt, exodus)

Iron Age – 1200 to 586 BC (Judges monarchy)

The Iron Age is further subdivided as follows:

Iron Age – 1200 to 1000 BC (Judges)

Iron Age IIA – 1000 to 900 BC (United monarchy)

Iron Age IIB – 900 to 700 BC (Divided monarchy)

Iron Age IIC – 700 to 586 BC (Fall of Samaria to fall of Jerusalem

The divisions between these periods are heuristic and do not correspond to precisely dated developments in metallurgy. For instance, some iron artifacts may be dated to the Bronze Age, though not widespread iron metalworking on an industrial scale. Especially in the various subdivisions of the Iron Age, transitions begin to be defined by political events rather than the metal sequence: Iron IA corresponds to the biblical period of the judges, Iron IIA to the united monarchy, Iron IIB to the divided monarchy, and Iron IIC to the period between the falls of Samaria and Jerusalem, when the southern kingdom alone had political autonomy. Some scholars round off the dates to avoid a periodization based on short-term political events and to emphasize the gradual rate of change in material culture and technology (e.g., using the round dates 900, 700, 600).

For events and dates after the fall of Jerusalem, historians employ a scheme of periodization based heavily on political factors. The series of periods are named for the dominant geopolitical powers in Syria-Palestine:

Neo-Babylonian period – 622 to 539 BC (Late Judean monarchy, exile)

Persian period – 539 to 330 BC (Return from exile)

Hellenistic period – 330 to 63 BC (Intertestamental)

Roman period – 63 BC to AD 324 (New Testament events

Although there was significant redaction (and, according to some, composition) of biblical texts in the Hellenistic period, no biblical narratives are ostensibly set in the period. Thus, the internal periodization of history in the Hebrew Bible ends with the return from exile (the Persian period).

New Testament

The birth of Jesus. According to Matt. 2:1 (see also Luke 1:5), Jesus was born during the lifetime of Herod the Great, who, as we know from Josephus, died in 4 BC (see Matt. 2:15–19). In his attempt to kill Jesus, Herod ordered the slaughter of male children up to the age of two, based on information that he obtained from the magi concerning the appearance of the star heralding Jesus’ birth (Matt. 2:16). Thus, Matthew’s account implies a date no later than 4 BC, but possibly several years earlier. Some scholars have attempted to correlate the magi’s observance of a star with one of several striking celestial phenomena, including a conjunction of Jupiter, Saturn, and Mars in 7 BC (so Johannes Kepler). Such attempts, however, are weakened by the fact that Matthew’s description of the star is vague, unnaturalistic, and difficult to identify certainly with a planetary alignment or any other known phenomenon (in particular, the star is said to move and then come to rest over Jesus’ location). Another line of investigation involves Luke’s correlation of Jesus’ birth with a Roman census that he dates to the time of Quirinius (Luke 2:1–2). This report, however, contradicts the testimony of Josephus, according to whom Quirinius became governor in AD 6 (a decade after the death of Herod). Most likely, Jesus was born shortly before 4 BC, during the reign of Herod.

The beginning and duration of Jesus’ public ministry. According to Luke 3:23, Jesus was “about thirty years old” at the time of his baptism and the beginning of his public ministry. In John 8:57, Jesus is challenged: “You are not yet fifty years old.” These two round numbers provide reasonable limits for the age of Jesus during his ministry. Owing to a paucity of chronological indicators in the Synoptic Gospels, the ministry of Jesus as depicted in Matthew, Mark, and Luke could have taken place within the space of a single year. In contrast, John narrates postbaptism events during three occurrences of the annual Passover festival (John 2:13; 6:4; 11:55), suggesting that Jesus’ ministry lasted for three years or longer. Unfortunately, the chronology of John appears in some instances to be at odds with the other Gospels. Most significantly, he places Jesus’ cleansing of the temple at the beginning, rather than the end, of his ministry (John 2:13–22; cf. Mark 11:15–19 pars.). It is unclear to what degree strict chronology has been modified in the interest of other concerns in each of the Gospels. According to John’s account, the cleansing of the temple occurred forty-six years after the beginning of its construction, an event that Josephus dates to either the eighteenth or the fifteenth year of Herod’s reign (John 2:20), placing the incident in the year AD 28 or 31. Ultimately, there are two sources of uncertainty pertaining to the chronology of Jesus’ ministry: the imprecise (and possibly symbolic) report of his age in Luke 3:23 and the indeterminate length of his ministry.

The death of Jesus. All four Gospels agree that Pontius Pilate, the Roman procurator of Judea, was instrumental in the trial and execution of Jesus. Pilate governed from AD 26 to 36; this provides a latest possible date for the death of Jesus. To refine the chronology beyond this, scholars have attempted to date the end of Jesus’ life based on its occurrence during the Feast of Passover (15 Nisan in the Jewish calendar) and by trying to determine in which year the feast would have coincided with his crucifixion on a Friday. This approach is complicated by the discrepancy between John, according to whom the Passover meal was eaten in the evening following the crucifixion (John 19:14), and Mark, who appears to have an imperfect knowledge of Passover customs (Mark 14:12–16) and thus describes Jesus’ final supper with his disciples as a Passover meal (i.e., on 14 Nisan). Following John’s chronology yields a date for the crucifixion of Friday, April 7 (Nisan 14), AD 30, or Friday, April 3 (Nisan 14), AD 33.

Of these two options, the AD 30 date conforms more closely to Luke 3:23, and it suggests that following a ministry of about three years, Jesus was in his mid- to late thirties at the time of his crucifixion.

Paul’s career. The chronology of Paul’s career remains a difficult question in biblical studies. There are two major sources for this chronology: the letters of Paul (esp. Galatians) and the book of Acts. When independent chronologies are constructed from each of these sources, several difficulties arise, including the absence of absolute anchors in Paul’s letters, lack of clear agreement between Acts and the letters regarding the number of visits to Jerusalem, and, by implication, the periodization of Paul’s career into distinct phases of concerted activity or “missionary journeys.” These data must in turn be synchronized, sometimes requiring some ingenuity, with other historically documented events such as the dating of Claudius’s edict (Acts 18:2), the dates of Aretas’s control of Damascus (2 Cor. 11:32–33), the death of Herod Agrippa in AD 44 (mentioned in Acts 12:23), the presence of Sergius Paulus in Cyprus during Paul’s first missionary journey (Acts 13:7 [this figure is known from inscriptions, but none of them clearly bears on the question]), and Festus’s succession of Felix as the procurator of Palestine (Acts 23–26), which Josephus puts in AD 53.

If we grant a fair measure of historical reliability to the outline of Acts, Paul experienced his conversion around AD 33, visited Jerusalem in AD 36 (Gal. 1:18), completed his first missionary journey and then visited Jerusalem to confer with the other apostles (Acts 15:1–29; Gal. 2:1) in the late 40s, conducted his second and third missionary journeys in the first half of the 50s before being finally arrested in Jerusalem around AD 57, and was taken to Rome in AD 59–60.
