Then the Lord said to Moses, “Leave this place. You and the people you brought up out of Egypt must leave it. Go up to the land I promised to give to Abraham, Isaac and Jacob. I said to them, ‘I will give it to your children after you.’
The Lord had spoken to Moses and Aaron. He had talked with them about the Israelites and about Pharaoh, the king of Egypt. He had commanded Moses and Aaron to bring the people of Israel out of Egypt.
So Moses and Aaron went to Pharaoh. They did exactly as the Lord had commanded them. Aaron threw the stick down in front of Pharaoh and his officials. It turned into a snake.
