2 Kings 6:8-12

8Now the king of Syria was warring against Israel; and he took counsel with his servants, saying, In such and such a place shall be my camp. 9And the man of God sent unto the king of Israel, saying, Beware that thou pass not such a place; for thither the Syrians are coming down. 10And the king of Israel sent to the place which the man of God told him and warned him of; and he saved himself there, not once nor twice. 11And the heart of the king of Syria was sore troubled for this thing; and he called his servants, and said unto them, Will ye not show me which of us is for the king of Israel? 12And one of his servants said, Nay, my lord, O king; but Elisha, the prophet that is in Israel, telleth the king of Israel the words that thou speakest in thy bedchamber.
