30 “When forty years had passed, an angel of the Lord appeared to him in the wilderness of Mount Sinai, in a flame of fire in a bush.
31 When Moses saw it, he marveled at the sight. As he drew near to look at it, the voice of the Lord came to him, saying,
32 ‘I am the God of your fathers, the God of Abraham and the God of Isaac and the God of Jacob.’ Moses trembled and dared not look.
33 “Then the Lord said to him, ‘Take off the shoes from your feet, for the place where you are standing is holy ground.
34 I have indeed seen the oppression of My people who are in Egypt. I have heard their groaning, and I have come down to deliver them. Now come, I will send you to Egypt.’
35 “This Moses, whom they rejected, saying, ‘Who appointed you a ruler and a judge?’ God sent as both ruler and redeemer by the hand of the angel who appeared to him in the bush.
36 He led them out after he had shown wonders and signs in the land of Egypt, and at the Red Sea, and for forty years in the wilderness.
