2 Samuel 20:9-20

9 And Joab said to Amasa, Art thou in health, my brother? And Joab took Amasa by the beard with the right hand to kiss him.
10 But Amasa took no heed to the sword that was in Joab's hand: so he smote him therewith in the fifth rib, and shed out his bowels to the ground, and struck him not again; and he died. So Joab and Abishai his brother pursued after Sheba the son of Bichri.
11 And one of Joab's men stood by him, and said, He that favoureth Joab, and he that is for David, let him go after Joab.
12 And Amasa wallowed in blood in the midst of the highway. And when the man saw that all the people stood still, he removed Amasa out of the highway into the field, and cast a cloth upon him, when he saw that every one that came by him stood still.
13 When he was removed out of the highway, all the people went on after Joab, to pursue after Sheba the son of Bichri.
14 And he went through all the tribes of Israel unto Abel, and to Bethmaachah, and all the Berites: and they were gathered together, and went also after him.
15 And they came and besieged him in Abel of Bethmaachah, 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.
