Genesis 21:18

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

“As for Ishmael, I have heard you; behold, I will bless him and will make him fruitful and will multiply him exceedingly. He shall become the father of twelve princes, and I will make him a great nation.

“And of the son of the maidservant I will make a nation also, because he is your seed.”

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