Judges 8:17-21

And he tore down the tower of Penuel and killed the men of the city.

Then he said to Zebah and Zalmunna, “Where were the men whom you killed at Tabor?” But they said, “You and they were alike, each one resembling the son of a king.”

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

So he said to Jether his firstborn, “Rise, kill them.” But the youth did not draw his sword, for he was afraid, because he was still a youth.

Then Zebah and Zalmunna said, “Rise up yourself, and attack us; for as the man, so is his strength.” So Gideon arose and killed Zebah and Zalmunna, and took the crescent amulets which were on their camels’ necks.
