Exodus 3:2 – 4
New International Version (NIV)
2 There the angel of the LORD appeared to him in flames of fire from within a bush. Moses saw that though the bush was on fire it did not burn up. 3 So Moses thought, “I will go over and see this strange sight — why the bush does not burn up.”
4 When 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.”
