'Send His Angel' in the Bible

Jehovah the God of the heavens, who took me out of my father's house, and out of the land of my nativity, and who has spoken to me, and who has sworn to me, saying, Unto thy seed will I give this land he will send his angel before thee, that thou mayest take a wife for my son thence.

And he said to me, Jehovah, before whom I have walked, will send his angel with thee, and prosper thy way, that thou mayest take a wife for my son of my family, and out of my father's house.

The Son of man shall send his angels, and they shall gather out of his kingdom all offences, and those that practise lawlessness;

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

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