21That is not the case. But a man named Sheba son of Bichri, from the hill country of Ephraim, has lifted up his hand against the king, against David. Deliver him alone, and I will depart from the city.” “Look,” the woman replied, “his head will be thrown to you over the wall.”
22Then the woman went to all the people with her wise counsel, and they cut off the head of Sheba son of Bichri and threw it to Joab. So he blew the ram’s horn and his men dispersed from the city, each to his own home. And Joab returned to the king in Jerusalem.
