John Wesley on Leviticus 26:44

For I am the Lord their God - Therefore neither the desperateness of their condition, nor the greatness of their sins, shall make me wholly make void my covenant with them and their ancestors, but I will in due time remember them for good, and for my covenant's sake return to them in mercy. From this place the Jews take great comfort, and assure themselves of deliverance out of their present servitude and misery. And from this, and such other places, St. Paul concludes, that the Israelitish nation, tho' then rejected and ruined, should be gathered again and restored.
