Exodus 3:2-4

2There the angel of the Lord appeared to him in a blazing fire from the middle of a bush. Moses stared in amazement. Though the bush was engulfed in flames, it didn’t burn up.

3“This is amazing,” Moses said to himself. “Why isn’t that bush burning up? I must go see it.”

4When the Lord saw Moses coming to take a closer look, God called to him from the middle of the bush, “Moses! Moses!” “Here I am!” Moses replied.
