2 Kings 6:5-6

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. {axe head: Heb. iron} 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.
