Acts 7:29-35

²⁹And Moses fled upon this word, and was a stranger in the land of Madian, where he begot two sons.

³⁰And when forty years were expired, there appeared to him in the desert of mount Sina, an angel in a flame of fire in a bush.

³¹And Moses seeing it, wondered at the sight. And as he drew near to view it, the voice of the Lord came unto him, saying:

³²I am the God of thy fathers; the God of Abraham, the God of Isaac, and the God of Jacob. And Moses being terrified, durst not behold.

³³And the Lord said to him: Loose the shoes from thy feet, for the place wherein thou standest, is holy ground.

³⁴Seeing I have seen the affliction of my people which is in Egypt, and I have heard their groaning, and am come down to deliver them. And now come, and I will send thee into Egypt.

³⁵This Moses, whom they refused, saying: Who hath appointed thee prince and judge? him God sent to be prince and redeemer by the hand of the angel who appeared to him in the bush.
