Exodus 3:2-5

21The angel of the Lord appeared to him in a blazing fire from the midst of 2a 3bush; and he looked, and behold, the bush was burning with fire, yet the bush was not consumed.

3So Moses said, “45I must turn aside now and see this 6marvelous sight, why the bush is not burned up.”

4When the Lord saw that he turned aside to look, 7God called to him from the midst of the bush and said, “Moses, Moses!” And he said, “Here I am.”

5Then He said, “Do not come near here; 8remove your sandals from your feet, for the place on which you are standing is holy ground.”
