Judges 8:18 KJV

16And he took the elders of the city, and thorns of the wilderness and briers, and with them he taught the men of Succoth.

17And he beat down the tower of Penuel, and slew the men of the city.

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

19And he said, They were my brethren, even the sons of my mother: as the LORD liveth, if ye had saved them alive, I would not slay you.

20And he said unto Jether his firstborn, Up, and slay them. But the youth drew not his sword: for he feared, because he was yet a youth.
