Judges 2:22

Or not. The secrets of hearts cannot be hidden from the omniscience of God. (Calmet) --- But he would have an experimental knowledge of the fidelity of his people, by leaving these nations in the midst of them. It was partly on this account that he withdrew the sword of Josue, who would otherwise have easily followed up his victories, and exterminated all the inhabitants. The cowardice and secret indispositions of the people was another obstacle. (Haydock) --- God acted like a person who distrusted the fidelity of his servant, and left something in his way to see if we would steal it. (Calmet)
