2 Samuel 20:22

Then Joab blew the trumpet, and the people returned from pursuing Israel, for Joab restrained the people.

And they took Absalom and cast him into a deep pit in the forest and set over him a very great heap of stones. And all Israel fled, each to his tent.

There was a small city with few men in it, and a great king came to it, surrounded it, and built large siegeworks against it.

But there was found in it a poor wise man, and he provided a way of escape for the city by his wisdom. Yet no one remembered that poor man.
