Judges 8:18-21 ESV
Then he said to Zebah and Zalmunna, “Where are the men whom you killed at Tabor?” They answered, “As you are, so were they. Every one of them resembled the son of a king.” And he said, “They were my brothers, the sons of my mother. As the LORD lives, if you had saved them alive, I would not kill you.” So he said to Jether his firstborn, “Rise and kill them!” But the young man did not draw his sword, for he was afraid, because he was still a young man. Then Zebah and Zalmunna said, “Rise yourself and fall upon us, for as the man is, so is his strength.” And Gideon arose and killed Zebah and Zalmunna, and he took the crescent ornaments that were on the necks of their camels.
