Amasa

"Amasa was not on his guard and failed to notice the sword in Joab’s left hand. Joab struck him with it in the belly so that his entrails poured forth to the ground. He did not find it necessary to strike a second blow, since Amasa had died instantaneously. Then Joab set forth with his brother Abishai in pursuit of Sheba, son of Bichri."

"Absalom had appointed Amasa to be commander of the army in Joab’s place. Amasa was the son of a man called Ithra the Ishmaelite who had married Abigail, the daughter of Nahash and the sister of Joab’s mother Zeruiah."

"Their sisters were Zeruiah and Abigail. The three sons of Zeruiah were Abishai, Joab, and Asahel."

"Now, you know what Joab, the son of Zeruiah, did to me, what he did to the two commanders of the army of Israel, to Abner, the son of Ner, and Amasa, the son of Jether. He killed them, shedding their blood during peacetime as if it were a time of war. The blood of battle is upon the belt around his waist and the sandals upon his feet."

"Thus the Lord will bring the blood back upon his own head. He struck down two men who were more righteous and better than he: Abner, the son of Ner, the commander of the army of Israel, and Amasa, the son of Jether, the commander of the army of Judah. He slew them with the sword, even though my father did not know about it."
