Leviticus 26:44

And yet for all that, when they be in the land of their enemies, when it seems that they are absolutely forsaken by God, I will not cast them away, neither will I abhor them to destroy them utterly, for that had not been the purpose of His punishment in the first place, and to break My covenant with them; for I am the Lord, their God, who always has mercy upon the repentant sinner.
