Acts 7:30-32

Williams(i) 30 When forty years had passed, an angel appeared to him in the desert of Mount Sinai, in the flame of a burning bush. 31 When Moses saw it, he wondered at the sight, and when he went up to look at it, the voice of the Lord said to him, 32 'I am the God of your forefathers, the God of Abraham, Isaac, and Jacob.' Moses was so terrified that he did not dare to look at the bush.
