Judges 8:18-21

18Then Gideon said to Zebah and Zalmunna, ‘Tell me about the men that you killed at Tabor. What kind of men were they?’ The kings answered, ‘They were like you. They looked like the sons of kings.’

19Gideon said, ‘Those were my brothers, my own mother's sons. If you had not killed my brothers, I would not kill you. I promise you that, as surely as the Lord lives.’

20Gideon said to his oldest son, Jether, ‘Kill them now!’ But Jether was only a boy. He was too afraid to do anything.

21Zebah and Zalmunna said to Gideon, ‘Kill us yourself! Let us see if you are brave enough to do that!’ So Gideon did kill them. He took away the silver images from the necks of their camels.
