What does Genesis 46:15 mean?
To escape a famine, Jacob's entire family is moving to Egypt (Genesis 45:9–11), under the care of his son, Joseph. This section lists all the sons and grandsons of Israel (Genesis 35:10) as they arrive. This verse summarizes and counts those listed so far: all sons and grandsons of Jacob's wife Leah.Each of the six sons listed—Reuben, Simeon, Levi, Judah, Issachar, and Zebulun—were born to Jacob outside of the Promised Land of Canaan in the region of Paddan-aram while he was working for his father-in-law. Dinah, the only of Jacob's daughters mentioned, was also born to Leah after all her sons were born (Genesis 30:21).
Dinah is not included in this count of Jacob's sons and grandsons with Leah, although Er and Onan are included in the tally of thirty-three. The final count given in Genesis 46:26–27, depicting those who actually entered Egypt, will include Dinah and exclude Er and Onan (Genesis 38:7, 9–10).
