Exodus 1:1-7

Now these are the names of the sons of Israel who came to Egypt with Jacob; each came with his household: Reuben, Simeon, Levi, and Judah; Issachar, Zebulun, and Benjamin; Dan and Naphtali, Gad, and Asher. All the descendants of Jacob were seventy people; Joseph was [already] in Egypt. Then Joseph died, and all his brothers and all that generation, but the Israelites were prolific and increased greatly; they multiplied and became extremely strong, so that the land was filled with them.
