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. Exodus:1-6 NLT

“Earth is crammed with heaven, and every common bush afire with God. But only he who sees takes off his shoes.” Aurora Leigh, Elizabeth Barrett Browning (1806 – 1861)
