2 Kings 6:7

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.

Now the king of Syria was at war against Israel; and he took counsel with his servants, saying, “My camp will be in such and such a place.”

The man of God sent to the king of Israel, saying, “Beware that you not pass this place, for the Syrians are coming down there.”

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 or twice.
