20:17 When he approached her, the woman asked, “Are you Joab?” He replied, “I am.” She said to him, “Listen to the words of your servant.” He said, “Go ahead. I’m listening.” 20:18 She said, “In the past they would always say, ‘Let them inquire in Abel,’ and that is how they settled things. 20:19 I represent the peaceful and the faithful in Israel. You are attempting to destroy an important city in Israel. Why should you swallow up the Lord’s inheritance?”
20:20 Joab answered, “Get serious! I don’t want to swallow up or destroy anything! 20:21 That’s not the way things are. There is a man from the hill country of Ephraim named Sheba son of Bicri. He has rebelled against King David. Give me just this one man, and I will leave the city.” The woman said to Joab, “This very minute his head will be thrown over the wall to you!”
20:22 Then the woman went to all the people with her wise advice and they cut off Sheba’s head and threw it out to Joab. Joab blew the trumpet, and his men dispersed from the city, each going to his own home. Joab returned to the king in Jerusalem.
