'Messenger' in the Bible

Jezebel sent a messenger to tell Elijah, "May the gods do the same to me and even more if tomorrow about this time I haven't made you like one of those prophets you had killed."

Meanwhile, the messenger who had gone off to summon Micaiah advised him, "Look, everything that the other prophets were saying was unanimously favorable to the king. So please, cooperate with them and speak favorably."
