Who are Angels?

11 Kings 19 vs. 35 – And it came to pass that night, that the angel of the Lord went out, and smote in the camp of the Assyrians an hundred fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses.

1. God uses angels to fight His enemies in this passage, an angel of God killed one hundred and eighty five thousands enemies of God.
