When the LORD saw him coming over to look at it more closely, God called out to him from the bush, "Moses! Moses!” He answered, “Here I am.” God said, “Come no nearer! Remove the sandals from your feet, for the place where you stand is holy ground. I am the God of your fathers, “ he continued, “the God of Abraham, the God of Isaac, the God of Jacob.” Moses hid his face, for he was afraid to look at God. (Ex 3:1-8a, 13-15)
