Deuteronomy 7:9-11

New Revised Standard Version, Anglicised

⁹ Know therefore that the Lord your God is God, the faithful God who maintains covenant loyalty with those who love him and keep his commandments, to a thousand generations, ¹⁰ and who repays in their own person those who reject him. He does not delay but repays in their own person those who reject him. ¹¹ Therefore, observe diligently the commandment—the statutes and the ordinances—that I am commanding you today.
