Deuteronomy 7:9-11

New Century Version

⁹ So know that the Lord your God is God, the faithful God. He will keep his agreement of love for a thousand lifetimes for people who love him and obey his commands. ¹⁰ But he will pay back those people who hate him. He will destroy them, and he will not be slow to pay back those who hate him. ¹¹ So be careful to obey the commands, rules, and laws I give you today.
