Exodus. Rubus Ardens.

Douay-Rheims translation

3:1. Now Moses fed the sheep of Jethro his father in law, the priest of Madian: and he drove the flock to the inner parts of the desert, and came to the mountain of God, Horeb.
3:2 And the Lord appeared to him in a flame of fire out of the midst of a bush: and he saw that the bush was on fire and was not burnt.
3:3 And Moses said: I will go and see this great sight, why the bush is not burnt.
3:4 And when the Lord saw that he went forward to see, he called to him out of the midst of the bush, and said: Moses, Moses. And he answered: Here I am.
3:5 And he said: Come not nigh hither, put off the shoes from thy feet: for the place whereon thou standest is holy ground.
3:6 And he said: I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob. Moses hid his face: for he durst not look at God.
3:7 And the Lord said to him: I have seen the affliction of my people in Egypt, and I have heard their cry because of the rigour of them that are over the works:
3:8 And knowing their sorrow, I am come down to deliver them out of the hands of the Egyptians, and to bring them out of that land into a good and spacious land, into a land that floweth with milk and honey, to the places of the Chanaanite, and Hethite, and Amorrhite, and Pherezite, and Hevite, and Jebusite.
3:9 For the cry of the children of Israel is come unto me: and I have seen their affliction, wherewith they are oppressed by the Egyptians.
3:10 But come, and I will send thee to Pharao, that thou mayst bring forth my people, the children of Israel out of Egypt.

4:1 Moses answered and said: They will not believe me, nor hear my voice, but they will say: The Lord hath not appeared to thee.
4:2 Then he said to him: What is that thou holdest in thy hand? He answered: A rod.
4:3 And the Lord said: Cast it down upon the ground. He cast it down, and it was turned into a serpent: so that Moses fled from it.
4:4 And the Lord said: Put out thy hand and take it by the tail. He put forth his hand, and took hold of it, and it was turned into a rod.
4:5 That they may believe, saith he, that the Lord God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared to thee.

4:17 And take this rod in thy hand, wherewith thou shalt do the signs.
4:18 Moses went his way, and returned to Jethro his father in law and said to him: I will go and return to my brethren into Egypt, that I may see if they be yet alive. And Jethro said to him: Go in peace.
