"40 If they shall confess their iniquity, and the iniquity of their fathers, with their trespass which they trespassed against me, and that also they have walked contrary unto me; 41 And that I also have walked contrary unto them, and have brought them into the land of their enemies; if then their uncircumcised hearts be humbled, and they then accept of the punishment of their iniquity: 42 Then will I remember my covenant with Jacob, and also my covenant with Isaac, and also my covenant with Abraham will I remember; and I will remember the land. 43 The land also shall be left of them, and shall enjoy her sabbaths, while she lieth desolate without them: and they shall accept of the punishment of their iniquity: because, even because they despised my judgments, and because their soul abhorred my statutes. 44 And yet for all that, when they be in the land of their enemies, I will not cast them away, neither will I abhor them, to destroy them utterly, and to break my covenant with them: for I am the LORD their God. 45 But I will for their sakes remember the covenant of their ancestors, whom I brought forth out of the land of Egypt in the sight of the heathen, that I might be their God: I am the LORD. 46 These are the statutes and judgments and laws, which the LORD made between him and the children of Israel in mount Sinai by the hand of Moses." — Leviticus 26:40-46 KJV.
MERCY AFTER JUDGMENTS — ISRAEL NOT UTTERLY DESTROYED, 40-46.40. If they shall confess — Confession implies conviction of sin and sincere repentance. David said, “I will confess my transgressions unto the Lord; and thou forgavest the iniquity of my sin.” And the iniquity of their fathers — So far as they had endorsed the iniquity of their fathers, by approving and imitating it, they were in a modified sense guilty. Thus must we repent not only of our actual sins but abhor their source, the poison stung into our nature by the transgression of our first parents. By so doing we obtain, through faith in Jesus Christ, not only justification from our personal sins, but the still greater blessing of entire sanctification from that corrupt state of heart which is technically called sin.
