2 Kings 6:1-6

Now the sons of the prophets said to Elisha, “Look now, the place where we live near you is too small for us. Please let us go to the Jordan [River] and let each man take from there a beam [for the building]; and let us make a place there for ourselves where we may live.” And he answered, “Go.” Then one said, “Please be willing to go with your servants.” So he answered, “I shall go.” So he went with them; and when they came to the Jordan, they cut down [some of] the trees. But it happened that as one was cutting down a beam, the axe head fell into the water; and he cried out and said, “Oh no, my master! It was borrowed!” The man of God said, “Where did it fall?” When he showed him the place, Elisha cut off a stick and threw it in there, and made the iron [axe head] float.
