Judges Chapter 3 Verse 8Therefore the anger of the LORD was hot against Israel, and he sold them into the hand of Chushanrishathaim king of Mesopotamia: and the children of Israel served Chushanrishathaim eight years.

I also will not henceforth drive out any from before them of the nations which Joshua left when he died:

That through them I may prove Israel, whether they will keep the way of the LORD to walk therein, as their fathers did keep [it], or not.

Therefore the LORD left those nations, without driving them out hastily; neither delivered he them into the hand of Joshua.

Now these [are] the nations which the LORD left, to prove Israel by them, [even] as many [of Israel] as had not known all the wars of Canaan;

Only that the generations of the children of Israel might know, to teach them war, at the least such as before knew nothing thereof;

[Namely], five lords of the Philistines, and all the Canaanites, and the Sidonians, and the Hivites that dwelt in mount Lebanon, from mount Baalhermon unto the entering in of Hamath.

And they were to prove Israel by them, to know whether they would hearken unto the commandments of the LORD, which he commanded their fathers by the hand of Moses.

And the children of Israel dwelt among the Canaanites, Hittites, and Amorites, and Perizzites, and Hivites, and Jebusites:

And they took their daughters to be their wives, and gave their daughters to their sons, and served their gods.

And the children of Israel did evil in the sight of the LORD, and forgat the LORD their God, and served Baalim and the groves.

And when the children of Israel cried unto the LORD, the LORD raised up a deliverer to the children of Israel, who delivered them, [even] Othniel the son of Kenaz, Caleb's younger brother.

And the Spirit of the LORD came upon him, and he judged Israel, and went out to war: and the LORD delivered Chushanrishathaim king of Mesopotamia into his hand; and his hand prevailed against Chushanrishathaim.

And the land had rest forty years. And Othniel the son of Kenaz died.

And the children of Israel did evil again in the sight of the LORD: and the LORD strengthened Eglon the king of Moab against Israel, because they had done evil in the sight of the LORD.

And he gathered unto him the children of Ammon and Amalek, and went and smote Israel, and possessed the city of palm trees.

So the children of Israel served Eglon the king of Moab eighteen years.

But when the children of Israel cried unto the LORD, the LORD raised them up a deliverer, Ehud the son of Gera, a Benjamite, a man lefthanded: and by him the children of Israel sent a present unto Eglon the king of Moab.

But Ehud made him a dagger which had two edges, of a cubit length; and he did gird it under his raiment upon his right thigh.

And he brought the present unto Eglon king of Moab: and Eglon [was] a very fat man.

And when he had made an end to offer the present, he sent away the people that bare the present.
