16 Then cried a wise woman out of the city, Hear, hear; say, I pray you, unto Joab, Come near hither, that I may speak with thee. 17 And he came near unto her; and the woman said, Art thou Joab? And he answered, I am. Then she said unto him, Hear the words of thy handmaid. And he answered, I do hear. 18 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]. 19 I am 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 Jehovah? 20 And Joab answered and said, Far be it, far be it from me, that I should swallow up or destroy. 21 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. 22 Then the woman went unto all the people in her wisdom. And they cut off the head of Sheba the son of Bichri, and threw it out to Joab. And he blew the trumpet, and they were dispersed from the city, every man to his tent. And Joab returned to Jerusalem unto the king.

Commentary on 2 Samuel 20:14-22
(Read 2 Samuel 20:14-22)
Justly is that place attacked, which dares to harbour a traitor; nor will the heart fare better which indulges rebellious lusts, that will not have Christ to reign over them. A discreet woman, by her prudent management, satisfied Joab, and yet saved the city. Wisdom is not confined to rank or sex; it consists not in deep knowledge; but in understanding how to act as matters arise, that troubles may be turned away and benefits secured. A great deal of mischief would be prevented, if contending parties would understand one another. Let both sides be undeceived. The single condition of peace is, the surrender of the traitor. It is so in God's dealing with the soul, when besieged by conviction and distress; sin is the traitor; the beloved lust is the rebel: part with that, cast away the transgression, and all shall be well. There is no peace on any other terms.
