2nd Kings 6:9

6 And the man of God said, Where fell it? And he showed him the place. And he cut down a stick, and cast it in thither, and made the iron to swim.

7 And he said, Take it up to thee. So he put out his hand, and took it.

8 Now 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.

9 And 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.

10 And 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.

11 And 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?

12 And 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.
