2 Samuel 5:6-9
6 And the king and his men went to Jerusalem to the Jebusites, the inhabitants of the land: who spoke to David, saying, Except thou shalt take away the blind and the lame, thou shalt not come in hither: thinking, David cannot come in hither.
7 Nevertheless, David took the strong hold of Zion: the same is the city of David.
8 And David said on that day, Whoever getteth up to the gutter, and smiteth the Jebusites, and the lame and the blind, that are hated by David's soul, he shall be chief and captain: Wherefore they said, The blind and the lame shall not come into the house.
9 So David dwelt in the fort, and called it the city of David. And David built around from Millo and inward.
2 Samuel 20:16-22
16 Then cried a wise woman out of the city, Hear, hear; say, I pray you, to Joab, Come near hither, that I may speak with thee.
17 And when he was come near to her, the woman said, Art thou Joab? And he answered, I am he. Then she said to him, Hear the words of thy handmaid. And he answered, I do hear.
18 Then she spoke, saying, They were wont to speak in old time, saying, They will 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 to Joab, Behold, his head shall be thrown to thee over the wall.
22 Then the woman went to 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 to the king.

5 A wise man is strong; and a man of knowledge increaseth strength.
Ecclesiastes 7:19
19 Wisdom strengtheneth the wise more than ten mighty men who are in the city.
Ecclesiastes 9:13-18
13 This wisdom have I seen also under the sun, and it seemed to me great:
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.
