Exodus 3:1-6

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. 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. “This is amazing,” Moses said to himself. “Why isn’t that bush burning up? I must go see it.” When 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. “Do not come any closer,” the LORD warned. “Take off your sandals, for you are standing on holy ground. I am the God of your father—the God of Abraham, the God of Isaac, and the God of Jacob.” When Moses heard this, he covered his face because he was afraid to look at God.
