Genesis
Chapter 21
17
And God heard the voice of the lad; and the angel of God called Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is.

Angel = Messenger, most likely Gabriel, in this case.
(Also Warrior, Protector, Defender, Keeper of the Faith)
