'Messenger' in the Bible

Now the messenger who went to summon Micaiah said to him, "Look, the prophets are in complete agreement that the king will succeed. Your words must agree with theirs; you must predict success!"

The Lord sent a messenger and he wiped out all the soldiers, princes, and officers in the army of the king of Assyria. So Sennacherib returned home humiliated. When he entered the temple of his god, some of his own sons struck him down with the sword.
