Deuteronomy 4:30-31

AKJV(i) 30 When you are in tribulation, and all these things are come on you, even in the latter days, if you turn to the LORD your God, and shall be obedient to his voice; 31 (For the LORD your God is a merciful God;) he will not forsake you, neither destroy you, nor forget the covenant of your fathers which he swore to them.
