'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 to me, and who swore to me, saying, To thy seed I will give this land: he will send his angel before thee, and thou shalt take a wife for my son from thence.

And he said to me, The LORD, 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.

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

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