Exodus 3:17-20

17I promise that I will bring you out of your troubles in Egypt. I will lead you into the land of the Canaanites, the Hittites, the Amorites, the Perizzites, the Hivites and the Jebusites. It is a land that will give you plenty of good food and drink, enough for everyone.’ ”

18When you say that, the leaders of the Israelites will listen to you. Then you must go with them to the king of Egypt. Say to him, “The Lord God has met with us. He is the God that we, the Israelite people, worship. So let us go on a journey into the wilderness. That will be a journey of three days. We must offer sacrifices to the Lord our God there.”

19But I know that the king of Egypt will not let you go. Only some great power will make him agree.

20So I will show him my power! I will do powerful miracles to punish the Egyptians. When they see that, Pharaoh will let you go free.
