2 Samuel 20:19-21

19I am one of those who are peaceable and faithful in Israel. You seek to destroy a city that is a mother in Israel. Why will you swallow up the heritage of the Lord?"

20Joab answered, "Far be it from me, far be it, that I should swallow up or destroy!

21That is not true. But a man of the hill country of Ephraim, called Sheba the son of Bichri, has lifted up his hand against King David. Give up him alone, and I will withdraw from the city." And the woman said to Joab, "Behold, his head shall be thrown to you over the wall."
