2 Samuel 20:20-21

And Joab answered and said, Far be it, far be it from me, that I should swallow up or destroy. The matter is not so: but a man of the hill-country of Ephraim, Sheba the son of Bichri by name, hath lifted up his hand against the king, even against David; deliver him only, and I will depart from the city. And the woman said unto Joab, Behold, his head shall be thrown to thee over the wall.
