2 Samuel 20:20-22

20And Joab replied, “Believe me, I don’t want to devour or destroy your town!

21That’s not my purpose. All I want is a man named Sheba son of Bicri from the hill country of Ephraim, who has revolted against King David. If you hand over this one man to me, I will leave the town in peace.” “All right,” the woman replied, “we will throw his head over the wall to you.”

22Then the woman went to all the people with her wise advice, and they cut off Sheba’s head and threw it out to Joab. So he blew the ram’s horn and called his troops back from the attack. They all returned to their homes, and Joab returned to the king at Jerusalem.
