2 Samuel 20:22

Then the woman in her wisdom went to all the people [to inform them of the agreement]. And they beheaded Sheba the son of Bichri and threw his head [down] to Joab. So he blew the trumpet [signaling the end of the attack], and they dispersed from the city, every man to his own tent. And Joab returned to Jerusalem to [David] the king. [Eccl 9:13-16]
