Exodus 3:3-6

3So Moses thought, “I will go over and see this strange sight—why the bush does not burn up.”

4When the LORD saw that he had gone over to look, God called to him from within the bush, “Moses! Moses!” And Moses said, “Here I am.” 5“Do not come any closer,” God said. “Take off your sandals, for the place where you are standing is holy ground.”

6Then he said, “I am the God of your father, Masoretic Text; Samaritan Pentateuch (see Acts 7:32) fathers the God of Abraham, the God of Isaac and the God of Jacob.” At this, Moses hid his face, because he was afraid to look at God.
