Deuteronomy 4:30-31

Thomson(i) 30 In thy affliction, when all these things have come upon thee in the latter days, when thou shalt turn to the Lord thy God, and hearken to his voice; 31 because the Lord thy God is a merciful God; he will not forsake thee utterly, nor totally destroy thee. He will not forget the covenant of thy fathers, which the Lord confirmed to them with an oath.
