“ Yahweh’s angel appeared to him in a flame of fire out of the middle of a bush. He looked, and behold, the bush burned with fire, and the bush was not consumed. Moses said, “I will go now, and see this great sight, why the bush is not burned.” When Yahweh saw that he came over to see, God called to him out of the middle of the bush, and said, “Moses! Moses!” He said, “Here I am.” He said, “Don’t come close. Take off your sandals, for the place you are standing on is holy ground.” Moreover he said, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob.” Moses hid his face because he was afraid to look at God.”
