'Send His Angel' in the Bible

Jehovah, the God of heaven, who took me from my father's house, and from the land of my nativity, and who spake unto me, and who sware unto me, saying, Unto thy seed will I give this land. He will send his angel before thee, and thou shalt take a wife for my son from thence.

And he said unto me, Jehovah, before whom I walk, will send his angel with thee, and prosper thy way. And thou shalt take a wife for my son of my kindred, and of my father's house.
