Mal'ak Elohim

" Hagar, return to Sarah. Do not be afraid, she will be kind. And you will bear a son who will grow to be a man fierce and passionate and one who will stir passions. Ishmael will be the father of a great nation". - Mal'ak Elohim talking to Hagar 
Mal'ak Elohim is an angel. He appears in several episodes. It is a theophany (physical manifestation) of God Himself. He was the fire that Moses saw burning in the bush. He was also the pillar of fire that led the Israelites out of Egypt. 
Genesis 22:15-18, the angel of the Lord swore by himself of all the blessings that would come to Abraham. We all know that GOD alone swears by no one but himself
