In context
1These are the names of the sons of Israel who went to Egypt with Jacob, each with his family: 2Reuben, Simeon, Levi, and Judah; 3Issachar, Zebulun, and Benjamin; 4Dan and Naphtali; 5The descendants of Jacob numbered seventy in all, including Joseph, who was already in Egypt. 6Now Joseph and all his brothers and all that generation died, 7but the Israelites were fruitful and increased rapidly; they multiplied and became exceedingly numerous, so that the land was filled with them.
