Genesis 16:8

And he said, Hagar, Sarai's maid, whence camest thou, and whither wilt thou go? And she said, I flee from the face of my mistress Sarai. From the entire story it is apparent that the angel speaking with Hagar is not an ordinary, created angel, but the Son of God, who even in the Old Testament was near His people and proved a very effective help to the patriarchs of Israel. Upon His calling Hagar by name and demanding an account of her coming and going, the slave gave a truthful answer. She herself was probably a believer in the true God, as a member of Abram's home congregation.
