2 Samuel 20
21 Ref The matter is not so: but a man of the hill-country of Ephraim, Sheba the son of Bichri by name, has lifted up his hand against the king, even against David; deliver him only, and I will depart from the city. The woman said to Joab, Behold, his head shall be thrown to you over the wall.
22 Ref Then the woman went to all the people in her wisdom. They cut off the head of Sheba the son of Bichri, and threw it out to Joab. He blew the trumpet, and they were dispersed from the city, every man to his tent. Joab returned to Jerusalem to the king.
