Judges 8:18-21

18He asked Zebah and Zalmunna, “What kind of men did you kill at Tabor?” “They were like you,” they said. “Each resembled the son of a king.”

19So he said, “They were my brothers, the sons of my mother! As the Lord lives, if you had let them live, I would not kill you.”

20Then he said to Jether, his firstborn, “Get up and kill them.” The youth did not draw his sword, for he was afraid because he was still a youth.

21Zebah and Zalmunna said, “Get up and strike us down yourself, for a man is judged by his strength.” So Gideon got up, killed Zebah and Zalmunna, and took the crescent ornaments that were on the necks of their camels.
