Judges 8:18-21
8:18 He said to Zebah and Zalmunna, “Describe for me the men you killed at Tabor.” They said, “They were like you. Each one looked like a king’s son.”
8:19 He said, “They were my brothers, the sons of my mother. I swear, as surely as the Lord is alive, if you had let them live, I would not kill you.”
8:20 He ordered Jether his firstborn son, “Come on! Kill them!” But Jether was too afraid to draw his sword, because he was still young.
8:21 Zebah and Zalmunna said to Gideon, “Come on, you strike us, for a man is judged by his strength.” So Gideon killed Zebah and Zalmunna, and he took the crescent-shaped ornaments which were on the necks of their camels.
