Exodus 3:2-4 ▼

2 And the angel of YHWH appeared to him in a flame of fire from the midst of the bush. And he looked, and behold, the bush was burning with the fire, and the bush was not consumed.

3 And Moses said, “Let me turn aside, please, and see this great sight. Why does the bush not burn?”

4 And YHWH saw that he had turned aside to look, and God called to him from the midst of the bush and He said, “Moses! Moses!” And he said, “Behold, it is I.”
