'Send His Angel' in the Bible

The LORD God of heaven which took me from my father's house and from the land where I was born, and which spake unto me and sware unto me saying 'unto thy seed will I give this land' - he shall send his angel before thee, that thou mayest take a wife unto my son from thence.

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