The Nations Left to Test Israel

31 Now these are the nations which Jehovah left, to prove Israel by them, even as many [of Israel] as had not known all the wars of Canaan; 2 only that the generations of the children of Israel might know, to teach them war, at the least such as beforetime knew nothing thereof: 3 [namely], the five lords of the Philistines, and all the Canaanites, and the Sidonians, and the Hivites that dwelt in mount Lebanon, from mount Baal-hermon unto the entrance of Hamath. 4 And they were [left], to prove Israel by them, to know whether they would hearken unto the commandments of Jehovah, which he commanded their fathers by Moses.

Commentary on Judges 3:1-7

(Read Judges 3:1-7)

As the Israelites were a type of the church on earth, they were not to be idle and slothful. The Lord was pleased to try them by the remains of the devoted nations they spared. Temptations and trials detect the wickedness of the hearts of sinners; and strengthen he graces of believers in their daily conflict with Satan, sin, and this evil world. They must live in this world, but they are not of it, and are forbidden to conform to it. This marks the difference between the followers of Christ and mere professors. The friendship of the world is more fatal than its enmity; the latter can only kill the body, but the former murders many precious souls.
