Judges 8:18-21

18Then said he to Zebah and Zalmunna, What sort of men were they that ye slew at Tabor? And they answered, As thou art, so were they; each one resembled the sons of a king.

19And he said, They were my brethren, the sons of my mother. [As] Jehovah liveth, if ye had saved them alive, I would not slay you.

20And he said to Jether his firstborn, Arise, slay them! But the youth drew not his sword; for he feared, because he was yet a youth.

21Then Zebah and Zalmunna said, Rise thou, and fall on us; for as is the man, so is his strength. And Gideon arose, and slew Zebah and Zalmunna; and he took the moons that were on their camels' necks.
