Acts 7
30 Ref At the end of forty years, an angel came to him in the waste land of Sinai, in the flame of a burning thorn-tree.
31 Ref And Moses, seeing it, was full of wonder, and when he came up to have a nearer view of it, the voice of the Lord came to him, saying,
32 Ref I am the God of your fathers, the God of Abraham and of Isaac and of Jacob. And Moses, shaking with fear, kept his eyes from looking at it.
33 Ref And the Lord said, Take off the shoes from your feet, for the place where you are is holy.
