2 Samuel 20:19-21

19I am among the peaceable and faithful in Israel. You seek to destroy a city and a mother in Israel. Why would you swallow up the inheritance of the Lord?”

20And Joab answered and said, “Far be it, far be it from me, that I should swallow up or destroy!

21That is not so. But a man from the mountains of Ephraim, Sheba the son of Bichri by name, has raised his hand against the king, against David. Deliver him only, and I will depart from the city.” So the woman said to Joab, “Watch, his head will be thrown to you over the wall.”
