2 Samuel 20:18-22

Then she spoke, saying, “In the past they used to say, ‘They will undoubtedly ask advice at Abel,’ and that is how they ended a dispute.

I am one of those who are ready for peace and faithful in Israel. You are trying to destroy a city, even a mother in Israel. Why would you swallow up the inheritance of the Lord?”

Joab replied, “Far be it, far be it from me that I would consume or destroy!

Such is not the case. But a man from the hill country of Ephraim, Sheba the son of Bichri by name, has raised his hand against King David. Only turn him over, and I will depart from the city.” And the woman said to Joab, “Behold, his head will be thrown to you over the wall.”

Then the woman wisely came to all the people. And they cut off the head of Sheba the son of Bichri and threw it to Joab. So he blew the trumpet, and they were dispersed from the city, each to his tent. Joab also returned to the king at Jerusalem.
