Exodus 3:2-4

Revised Standard Version

² And the angel of the Lord appeared to him in a flame of fire out of the midst of a bush; and he looked, and lo, the bush was burning, yet it was not consumed. ³ And Moses said, “I will turn aside and see this great sight, why the bush is not burnt.” ⁴ When the Lord saw that he turned aside to see, God called to him out of the bush, “Moses, Moses!” And he said, “Here am I.”
