Now these are the names of the children of Israel who came to Egypt; each man and his household came with Jacob:
Reuben, Simeon, Levi, and Judah;
Issachar, Zebulun, and Benjamin;
Dan, Naphtali, Gad, and Asher.
All those who were descendants of Jacob were seventy persons (for Joseph was in Egypt already).
References for Exodus 1:5
And Joseph died, all his brothers, and all that generation.
But the children of Israel were fruitful and increased abundantly, multiplied and grew exceedingly mighty; and the land was filled with them.
