2 Kings 6:3

The sons of the prophets said to Elisha, “See now, the place where we live and meet with you is too small for us.

Please let us go to the Jordan, and each man take a beam from there, and let’s make us a place there, where we may live.”

He answered, “Go!”

So he went with them. When they came to the Jordan, they cut down wood.

But as one was cutting down a tree, the ax head fell into the water. Then he cried out and said, “Alas, my master! For it was borrowed.”

The man of God asked, “Where did it fall?” He showed him the place. He cut down a stick, threw it in there, and made the iron float.
