Judges 8:20-21

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.
