Exodus 1:1-7 (ESV)

1 These are the names of the sons of Israel who came to Egypt with Jacob, each 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 persons; Joseph was already in Egypt. Then Joseph died, and all his brothers and all that generation. But the people of Israel were fruitful and increased greatly; they multiplied and grew exceedingly strong, so that the land was filled with them.
