Acts 7:8-9

8Then God made an covenant with Abraham that his descendants would be his special people. God said, “You must circumcise all your baby boys.” Later, Abraham became the father of Isaac. Abraham circumcised Isaac when he was eight days old. Then Isaac became the father of Jacob. Jacob himself had 12 sons. These sons became the 12 ancestors of the families of Israel.

9One of Jacob's sons was called Joseph. Jacob was more kind to Joseph than to his other sons. For this reason, Joseph's brothers did not like him. So one day they took Joseph and they sold him as a slave. The men that bought Joseph took him to Egypt. There he became the slave of an important man. All this time, God took care of Joseph.
