'Send His Angel' in the Bible

The LORD God of heaven, who took me from my father's house, and from the land of my kindred, and who spoke unto me, and that swore unto me, saying, Unto your descendants will I give this land; he shall send his angel before you, and you shall take a wife unto my son from there.

And he said unto me, The LORD, before whom I walk, will send his angel with you, and prosper your way; and you shall take a wife for my son of my kindred, and of my father's house:

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

And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
