18 Then he said to Zebah and Zalmunna, Where are the men whom you put to death at Tabor? And they gave answer, As you are, so were they; every one of them was like a king's son. 19 And he said, They were my brothers, my mother's sons: by the life of the Lord, if you had kept them safe, I would not put you to death. 20 Then he said to Jether, his oldest son, Up! Put them to death. But the boy did not take out his sword, fearing because he was still a boy. 21 Then Zebah and Zalmunna said, Up! Put an end to us yourself: for you have a man's strength. Then Gideon got up and put Zebah and Zalmunna to death and took the ornaments which were on their camels' necks.

Commentary on Judges 8:18-21
(Read Judges 8:18-21)
The kings of Midian must be reckoned with. As they confessed themselves guilty of murder, Gideon acted as the avenger of blood, being the next of kin to the persons slain. Little did they think to have heard of this so long after; but murder seldom goes unpunished in this life. Sins long forgotten by man, must be accounted for to God. What poor consolation in death from the hope of suffering less pain, and of dying with less disgrace than some others! yet many are more anxious on these accounts, than concerning the future judgment, and what will follow.
