Deuteronomy 7:9-11

New King James Version

⁹ “Therefore know that the Lord your God, He is God, ^(A)the faithful God ^(B)who keeps covenant and mercy for a thousand generations with those who love Him and keep His commandments; ¹⁰ and He repays those who hate Him to their face, to destroy them. He will not ^[a]be ^(C)slack with him who hates Him; He will repay him to his face. ¹¹ Therefore you shall keep the commandment, the statutes, and the judgments which I command you today, to observe them.
