8 They troubled and oppressed the children of Israel that year: eighteen years (oppressed they) all the children of Israel that were beyond the Jordan in the land of the Amorites, which is in Gilead.

That year - Perhaps the closing year of the oppression, when the Ammonites passed over the Jordan. For it was this crowning oppression which brought the Israelites to repentance Judges 10:10, Judges 10:15-16, and so prepared the way for the deliverance. Possibly in the original narrative from which this portion of the Book of Judges is compiled, "that year" was defined.
The land of the Amorites - Namely, of Sihon king of the Amorites, Numbers 21:21; Deuteronomy 1:4; Joshua 13:10; Psalm 135:11.
And that year they vexed and oppressed the children of Israel: eighteen years, (b) all the children of Israel that [were] on the other side Jordan in the land of the Amorites, which [is] in Gilead.
(b) As the Reubenites, Gadites, and half the tribe of Manasseh.
And that year they vexed and oppressed the children of Israel,.... The Philistines on one side, and the children of Ammon on the other; meaning either that year in which Jair died, as Jarchi; or the first year they began to bring them into bondage, as R. Isaiah: "and from that year", as Kimchi and Ben Melech, that they vexed and distressed them, they continued to vex and distress them
eighteen years; or, as Abarbinel interprets it, "with that year", they vexed and oppressed them eighteen years, that is, so many more, or reckoning that into the number of them; and these eighteen years of their oppression are not to be reckoned into the years of Jair's government, and as commencing from the fourth of it, as Bishop Usher, Lightfoot, and others; for it does not appear that there was any oppression in his days, but from the time of his death to the raising up of Jephthah a new judge: and the people oppressed by the children of Ammon during that time
were all the children of Israel that were on the other side Jordan, in the land of the Ammonites, which is in Gilead; even the tribes of Reuben and Gad, and the half tribe of Manasseh.
That year - Or, that year they had vexed and oppressed the children of Israel eighteen years - This was the eighteenth year from the beginning of that oppression. And these eighteen years are not to be reckoned from Jair's death, because that would enlarge the time of the judges beyond the just bounds; but from the fourth year of Jair's reign: so that the greatest part of Jair's reign was contemporary with this affliction. The case of Jair and Samson seem to be much alike. For as it is said of Samson, that he judged Israel in the days of the tyranny of the Philistines, twenty years, Judges 15:20, by which it is evident, that his judicature, and their dominion, were contemporary; the like is to be conceived of Jair, that he began to judge Israel, and endeavoured to reform religion, and purge out all abuses; but being unable to effect this through the backwardness of the, people, God would not enable him to deliver the people, but gave them up to this sad oppression; so that Jair could only determine differences amongst the Israelites, but could not deliver them from their enemies.
