That through them I may prove Israel
Afflict them by them, and so prove or try them, their faith and patience, which are tried by afflictions; and such were the Canaanites to them, as afflictions and temptations are to the spiritual Israel of God; or rather, whether they would keep in the ways of God, or walk in those the Canaanites did, as follows:
whether they will keep the way of the Lord, as their fathers did keep
[it], or not;
whether they would worship the true God their fathers did, or the gods of the Canaanites; not that the Lord was ignorant of what they would do, and so made the experiment; but that the sincerity and faithfulness, or insincerity and unfaithfulness of their hearts, might appear to themselves and others.
