2 Kings 6:8-10

Once when the king of Syria was warring against Israel, he took counsel with his servants, saying, “At such and such a place shall be my camp.” But the man of God sent word to the king of Israel, “Beware that you do not pass this place, for the Syrians are going down there.” And the king of Israel sent to the place about which the man of God told him. Thus he used to warn him, so that he saved himself there more than once or twice.
