Exodus 3
So Moses becomes a shepherd for his father-in-law Jethro, the priest of Midian. Leading the flock, he goes to Horeb, the mountain of the true God. There God’s angel appears to him in a flame. He wants to get closer but god tells him it is holy ground so he must take his sandals off. And he tells him that he wants to keep his promise to bring Israel to the promised land. And he tells Moses that he will send him to Egypt to bring his people to the promised land. Then Moses will tell the Israelites that he come from God that he is sent by “I AM THAT I AM”, “I AM hath sent me unto you”, “the LORD God of your fathers, the God of Abraham, the God of Isaac and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations”. So Moses must tell the elders of Israel and asks Pharaoh for a three-day journey into the wilderness to make sacrifices to God. But Pharaoh will refuse and God will strike the Egyptians so Pharaoh will finally let the Israelites to go away and bring with them gold and silver and clothes.
