'Messenger' in the Bible

Jezebel sent a messenger to Elijah with this warning, "May the gods judge me severely if by this time tomorrow I do not take your life as you did theirs!"

He stretched out and fell asleep under the shrub. All of a sudden an angelic messenger touched him and said, "Get up and eat."

The Lord's angelic messenger came back again, touched him, and said, "Get up and eat, for otherwise you won't be able to make the journey."

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."
