Judges 3:4

And they were to prove Israel by them ,.... They were left in the land, as to inure them to war, and try their courage, so to prove their faithfulness to God:

to know whether they would hearken to the commandments, of the Lord ,

which he commanded their fathers by the hand of Moses ; even all the commandments of the Lord delivered to them by Moses, moral, civil, and ceremonial, and particularly those that concerned the destruction of the Canaanites, their altars, and their idols, Deuteronomy 7:1 .
