The following material summarizes some of the arguments for an early date () and a later date () of the exodus. The archaeological claims of each side have all been challenged by the other side, but the details of such responses are not included here.
Arguments for an Early Date of the Exodus
These arguments are used to support an "early date" () for the exodus:
1.First Kings 6:1 says, "In the four hundred and eightieth year after the people of Israel came out of the land of Egypt, in the fourth year of Solomon's reign over Israel . . . he began to build the house of the Lord." The currently accepted date for the fourth year of Solomon's reign is , and before that would be . This is supported by 1 Chronicles 6:33-37, which names 18 generations from Korah (in the time of Moses) to Heman (in the time of David), which then requires 19 generations from Moses to Solomon. Nineteen generations in works out to an average of , a reasonable number that gives confirmation to an actual in 1 Kings 6:1.
2. In Judges 11:26, Jephthah's message to the king of the Ammonites says that Israel had already lived in Canaan for "." This message is dated to around , which would yield a date of for entrance into the land of Canaan, which is consistent with a exodus.
3. Archaeological data from Jericho, Ai, and Hazor have been claimed to show evidence of destruction in the , which is consistent with a exodus and conquest of Canaan. But there is no evidence of occupation of Jericho in the (as would be required by a later date for the exodus).
4. The Amarna Letters show that Canaanite kings in the wrote letters to Pharaoh pleading for help against the ‘apiru who were "taking over" the lands of Canaan. This is consistent with dating the beginning of the conquest by Israel at .
5.Exodus 1:11, which mentions the building of "Raamses," should not be dated to (as a "late date" view would hold), because the remarkable multiplication of Israel (Ex. 1:12-22) and the birth of Moses (Ex. 2:2) both occur after Exodus 1:11. But if Moses was "eighty years old" (Ex. 7:7) when he led the people out of Egypt, this would put the exodus at least after the building of Raamses, or , which is far too late on either scheme. In fact, the Merneptah Stele (an inscribed tombstone-like stone slab) describes a military triumph over Israel in Canaan in
6. With an early date for the exodus, the time of the Judges takes about . This is generally consistent with the book of Judges itself, where a simple addition of the length of the reigns of the individual judges gives just over , and this can be reduced to if there was overlapping of some reigns, but it cannot reasonably be reduced to as little as , as would be required by the proposed later date for the exodus.
Arguments for a Later Date of the Exodus
In favor of a "later date" () are the following arguments:
1.Exodus 1:11 says the Israelites "built for Pharaoh store cities, Pithom and Raamses." But the city of Raamses (also spelled Rameses; the Egyptian Pi-Rameses) was built by Raamses II, who reigned This city is not mentioned in any earlier archaeological records from Egypt. Therefore the Israelites were still in Egypt when Raamses was built. In addition, the other geographical terms in Exodus--e.g., Pithom, Migdol, Yam Sup (the "Red Sea"), etc.--are all attested in Egyptian texts, whereas they are not attested in the period of the early date.
2.First Kings 6:1 probably uses the expression "" as a representative number to stand for 12 idealized generations of each. But in reality the period covered 12 generations of only each, or . Subtracting from gives an exodus .
3. Egypt had imperial control over Canaan from But there is no Egyptian record of any military conflicts with Israel over that land until the Merneptah Stele, which refers to a victory over Israel
4. The Bible contains almost no mention of conflict with Egypt in Joshua or Judges, which would be strange if the Israelites entered Canaan in , when the Egyptian Empire had control over Canaan. This makes a late date for the exodus more likely, since Egyptian influence over Canaan was minimal after
5. The covenant forms used at the time of Moses in the biblical narratives show significant parallels to ancient Near Eastern covenants in the but not in the
6. Archaeological discoveries in Canaan show the complete destruction of some cities (such as Hazor) in the , which would fit with a date of for the exodus. Further, site surveys seem to show that there was a huge migration into the hill country areas of Canaan in the There also appear to have been technological innovations in this later period, such as terracing of the land, newer pottery styles, and plaster-lined silos, that favor the later date for Israel's occupation.
Conclusion
Both the early date and the late date are supported by established evangelical scholars today. In this Study Bible, both the early date () and the later date () are included.
The Hebrew Calendar Compared to the Gregorian (Modern) Calendar
The Hebrew calendar was composed of 12 lunar months, each of which began when the thin crescent moon was first visible at sunset. They were composed of approximately and were built around the agricultural seasons. Apparently some of the names of the months were accommodated from Babylon following the time that the Israelites were exiled there.
