Exodus 2:15; Exodus 2:23

15 And sure enough, Pharaoh heard what had happened, and he tried to kill Moses. But Moses fled from Pharaoh and went to live in the land of Midian. When Moses arrived in Midian, he sat down beside a well.
23 Years passed, and the king of Egypt died. But the Israelites continued to groan under their burden of slavery. They cried out for help, and their cry rose up to God.
