Genesis 21:17

After these things the word of Yahweh came to Abram in a vision, saying, “Do not fear, Abram, I am a shield to you; Your reward shall be very great.”

Now the angel of Yahweh found her by a spring of water in the wilderness, by the spring on the way to Shur.

But the angel of Yahweh called to him from heaven and said, “Abraham, Abraham!” And he said, “Here I am.”

“Yahweh, the God of heaven, who took me from my father’s house and from the land of my kin, and who spoke to me and who swore to me, saying, ‘To your seed I will give this land,’ He will send His angel before you, and you will take a wife for my son from there.

And the angel of Yahweh appeared to him in a blazing fire from the midst of the bush; and he looked, and behold, the bush was burning with fire, yet the bush was not consumed.
