2 Samuel 20:19 (KJV)

And when he was come near unto her, the woman said, Art thou Joab? And he answered, I am he. Then she said unto him, Hear the words of thine handmaid. And he answered, I do hear.

Then she spake, saying, They were wont to speak in old time, saying, They shall surely ask counsel at Abel: and so they ended the matter.

I am one of them that are peaceable and faithful in Israel: thou seekest to destroy a city and a mother in Israel: why wilt thou swallow up the inheritance of the Lord?

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 mount 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.
