So [to humiliate them] Gideon said to Jether his firstborn, “Stand up, and kill them!” But the youth did not draw his sword, because he was afraid, for he was still [just] a boy.

Now you also know what Joab the son of Zeruiah [my sister] did to me, and what he did to the two commanders of the armies of Israel, to Abner the son of Ner and to Amasa the son of Jether, [both of] whom he murdered; avenging the blood of war in [a time of] peace. And he put the [innocent] blood of war [of Abner and Amasa] on his belt that was around his waist, and on his sandals on his feet.

The Lord will return his bloody deeds upon his own head, because he struck down two men more righteous and honorable than he and killed them with the sword, without my father David knowing: Abner the son of Ner, commander of the army of Israel, and Amasa the son of Jether, commander of the army of Judah.
