'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.

And he shall send his angels with the great voice of a trumpet, and they shall gather together his chosen from the four winds, and from the one end of the world to the other.

And then shall he send his angels, and shall gather together his elect from the four winds, and from the one end of the world to the other.
