Daniel 3:25

He answered and said, Lo, I see four men loose, no longer bound as they had been cast in, walking in the midst of the fire, not leaving it, but waiting for God's time to leave them out, and they have no hurt, as one might have expected by reason of the rough treatment accorded them; and the form of the fourth, on account of the compelling dignity of his appearance, is like the son of God, rather, "like a son of the gods," one pertaining to a divine family and generation. The fourth man was an angel of God, sent for the protection of His pious servants, so that the flame could not harm them. God protects those who place their trust in Him in the midst of death and destruction, so that not a hair may fall from their heads without His will.
