The right man was a woman

Ecclesiastes 9
[13] This wisdom have I seen also under the sun, and it seemed great unto me:
[14] There was a little city, and few men within it; and there came a great king against it, and besieged it, and built great bulwarks against it:
[15] Now there was found in it a poor wise man, and he by his wisdom delivered the city; yet no man remembered that same poor man.
[16] Then said I, Wisdom is better than strength: nevertheless the poor man's wisdom is despised, and his words are not heard.
[17] The words of wise men are heard in quiet more than the cry of him that ruleth among fools.
[18] Wisdom is better than weapons of war: but one sinner destroyeth much good.

II Samuel 20
[14] And he went through all the tribes of Israel unto Abel, and to Beth-maachah, and all the Berites: and they were gathered together, and went also after him.
[15] And they came and besieged him in Abel of Beth-maachah, and they cast up a bank against the city, and it stood in the trench: and all the people that were with Joab battered the wall, to throw it down.
[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 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.
[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 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?
[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 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.
[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 cast it out to Joab. And he blew a trumpet, and they retired from the city, every man to his tent. And Joab returned to Jerusalem unto the king.
