2 Kings 6:9 (KJV)

So he went with them. And when they came to Jordan, they cut down wood.

But as one was felling a beam, the axe head fell into the water: and he cried, and said, Alas, master! for it was borrowed.

And the man of God said, Where fell it? And he shewed him the place. And he cut down a stick, and cast it in thither; and the iron did swim.

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

Then the king of Syria warred against Israel, and took counsel with his servants, saying, In such and such a place shall be my camp.

And the king of Israel sent to the place which the man of God told him and warned him of, and saved himself there, not once nor twice.

Therefore 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 shew me which of us is for the king of Israel?

And one of his servants said, None, 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.

And he said, Go and spy where he is, that I may send and fetch him. And it was told him, saying, Behold, he is in Dothan.

Therefore sent he thither horses, and chariots, and a great host: and they came by night, and compassed the city about.
