(20) And he said unto Jether.--By the jus talionis. as well as by every other consideration of that time, Gideon, as the last survivor of all his kingly brothers, would hold himself justified in putting his captives to death. Jether also would inherit the duties of goel (Numbers 35:12; 2Samuel 2:22, &c), and Gideon desired both to train the boy to fearlessness against the enemies of Israel (Joshua 10:24-25). to give him prestige, and to add to the disgrace of the Midianite kings. Again. Gideon must only be judged by the standard and the customs of his own day. (Comp. 1Samuel 15:33, Samuel and Agag; 2Samuel 1:15, David and the Amalekite.) The name Jether is another form of Jethro and means "pre-eminence."

Verse 20. - He said unto Jether, etc. These marks of savage life are painful to contemplate in such a man as Gideon. But it is well for us to be made aware how the best and greatest men cannot rise above the manners and received maxims of their age; and it teaches us to make due allowance for the faults of uncivilised men with whom we have to do, whether Afghans, or Zulus, or others.

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.And he said unto Jether, his firstborn, up, and slay them,.... Being the near kinsman of his father's brethren, whom these kings had slain, was a proper person to avenge their blood on them; and the rather Gideon might order him to do it, for the greater mortification of the kings, to die by the hand of a youth; and for the honour of his son, to be the slayer of two kings, and to inure him to draw his sword against the enemies of Israel, and embolden him to do such exploits:

but the youth drew not his sword, for he feared, because he was yet a youth; his not drawing is sword was not out of disobedience to his father, but through fear of the kings; not of their doing him any harm, being bound; but there was perhaps a ferocity, as well as majesty in their countenances, which made the young man timorous and fearful.
