Exodus 3:2-4 Holman Christian Standard Bible (HCSB)
2 Then the Angel of the Lord appeared to him in a flame of fire within a bush. As Moses looked, he saw that the bush was on fire but was not consumed. 3 So Moses thought: I must go over and look at this remarkable sight. Why isn’t the bush burning up?
4 When the Lord saw that he had gone over to look, God called out to him from the bush, “Moses, Moses!”
“Here I am,” he answered.
