God commanded Moses to rescue the Jewish people from Egypt.

Acts 7:30-34

30 “One day 40 years later, the Lord God appeared as an angel to Moses. He appeared in a bush that was burning in the desert near Sinai Mountain. 31 When Moses saw that, he was greatly surprised, because the bush was not burning up. As he went over to look more closely, he heard the Lord God say to him, 32 ‘I am the God whom your ancestors worshipped. I am the God that Abraham, Isaac and Jacob worship.’ Moses was so afraid that he began to shake. He was afraid to look at the bush any longer. 33 Then the Lord God said to him, ‘Take your sandals off to show that you(sg) revere me. Because I am here, the place where you are standing is holy/sacred. 34 I have surely seen how the people of Egypt are continually causing my people to suffer. I have heard my people when they groan because those people continually oppress them. So I have come down to rescue them from Egypt. Now get ready, because I am going to send you back to Egypt to do that.’ ”
