Abishai: Defeats the Ammonites
Source: Nav
2 Samuel 10:10, 14
And he placed the rest of the forces under the command of his brother Abishai, who arrayed them against the Ammonites. / When the Ammonites saw that the Arameans had fled, they too fled before Abishai, and they entered the city. So Joab returned from fighting against the Ammonites and came to Jerusalem.
