The Post Flood period began from 2370 BC to the covenant that God made with Abraham.
- From the beginning of the Flood
- to Arpachshad’s birth 2 years
- Then to the birth of Shelah 35 years
- To the birth of Eber 30 years
- To the birth of Peleg 34 years
- To the birth of Reu 30 years
- To the birth of Serug 32 years
- To the birth of Nahor 30 years
- To the birth of Terah 29 years
- To the death of Terah, when
- Abraham was 75 years old 205 years
- Total 427 years
The basis for these figures is Genesis 11:10 to 12:4. The expression “after the deluge” (Ge 11:10) used in connection with Arpachshad’s birth would logically refer to the actual falling of the waters that marked the start of the Flood (2370 B.C.E.), rather than simply to the continuance of the waters upon the earth for a period of time thereafter. The Hebrew term for “deluge” also indicates this.—Compare Ge 6:17; 7:4-6, 10-12, 17; 9:11.
The date of the attempt at building the Tower of Babel is not stated in the record. Genesis 10:25 indicates that the division resulting from the confusion of the languages there occurred sometime during ‘the days of Peleg.’ It does not necessarily follow that this event occurred at Peleg’s birth. The expression “in his days” would in fact indicate that the division took place, not at or immediately subsequent to Peleg’s birth, but sometime during his life span, which extended from 2269 to 2030 B.C.E. If each post-Flood male parent at the age of 30 were to begin fathering children at the rate of one child every three years, with an average of one male child every six years, and continued this until the age of 90, then in a period of about 180 years from the end of the Flood (that is, by 2189 B.C.E.) the population could have grown to a total of over 4,000 adult males. This conservative number would be ample to fit the circumstances relating to the tower construction and the dispersal of the peoples.
Evidently at the time of Abraham’s crossing the Euphrates on his way to the land of Canaan, Jehovah validated with him what has come to be known as the Abrahamic covenant. As Abraham’s departure from Haran and his entry into Canaan followed the death of his father Terah, the date of the validating of this covenant is set at 1943 B.C.E.—Ge 11:32; 12:1-5.
