Exodus 3:1-4

1 One day Moses was tending the flock of his father-in-law, Jethro, the priest of Midian. He led the flock far into the wilderness and came to Sinai, the mountain of God. 2 There 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.” 4 When the Lord saw Moses coming to take a closer look, God called to him from the middle of the bush, “Moses! Moses!”
