Now Abishai, the brother of Joab, the son of Zeruiah, was chief of the thirty. And he swung his spear against three hundred who were slain by him; and he had a name as well as the three.
Now the sons of Ammon saw that the Arameans fled. So they also fled before Abishai and came into the city. Then Joab returned from fighting against the sons of Ammon and came to Jerusalem.
And David sent the people out, one-third under the hand of Joab, one-third under the hand of Abishai the son of Zeruiah, Joab’s brother, and one-third under the hand of Ittai the Gittite. And the king said to the people, “I myself will surely go out with you also.”
But Amasa was not on guard against the sword which was in Joab’s hand so he struck him in the belly with it and poured out his inward parts on the ground, and did not strike him again, and he died. Then Joab and Abishai his brother pursued Sheba the son of Bichri.
