Exodus 1:1-5

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).
