4 They were (left), to prove Israel by them, to know whether they would listen to the commandments of Yahweh, which he commanded their fathers by Moses.

To know whether they would hearken - This would be the consequence of the Canaanites being left among them: if they should be faithful to God, their enemies would not be able to enslave them; should they be rebellious, the Lord would abandon them to their foes.
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.
To know - That is, that they and others might know by experience.
