Acts 7:30-34

30“When forty years had passed, an angel appeared to him in the wilderness of Mount Sinai in the flame of a burning bush.

31When Moses saw it, he was amazed at the sight. But when he came up to look, there came the voice of Adonai:

32‘I am the God of your fathers, the God of Abraham and Isaac and Jacob.’ “Moses trembled in fear and did not dare to look.

33But Adonai said to him, ‘Take the sandals off your feet, for the place where you are standing is holy ground.

34I have surely seen the oppression of my people in Egypt and have heard their groaning, and I have come down to deliver them. Now come—let Me send you to Egypt.’
