'Messenger' in the Bible

And the messenger who hath gone to call for Micaiah hath spoken unto him, saying, 'Lo, the words of the prophets -- one mouth -- are good towards the king, and let, I pray thee, thy word be like one of theirs: and thou hast spoken good.'

and Jehovah sendeth a messenger, and cutteth off every mighty one of valour -- both leader and head -- in the camp of the king of Asshur, and he turneth back with shame of face to his land, and entereth the house of his god, and those coming out of his bowels have caused him to fall there by the sword.
