These are the names of the sons of Israel (that is, Jacob) who moved to Egypt with their father, each with his family: Reuben, Simeon, Levi, Judah, Issachar, Zebulun, Benjamin, Dan, Naphtali, Gad, and Asher. In all, Jacob had seventy descendants in Egypt, including Joseph, who was already there.
In time, Joseph and all of his brothers died, ending that entire generation. But their descendants, the Israelites, had many children and grandchildren. In fact, they multiplied so greatly that they became extremely powerful and filled the land.
