2 Samuel 20:20-22

New King James Version

²⁰ And Joab answered and said, “Far be it, far be it from me, that I should swallow up or destroy! ²¹ That is not so. But a man from the mountains of Ephraim, Sheba the son of Bichri by name, has raised his hand against the king, against David. Deliver him only, and I will depart from the city.”

So the woman said to Joab, “Watch, his head will be thrown to you over the wall.” ²² Then the woman ^(A)in her wisdom went to all the people. And they cut off the head of Sheba the son of Bichri, and threw it out to Joab. Then he blew a trumpet, and they withdrew from the city, every man to his tent. So Joab returned to the king at Jerusalem.
