Deuteronomy 7 9-11

From this you can know that Adonai your God is indeed God, the faithful God, who keeps his covenant and extends grace to those who love him and observe his mitzvot, to a thousand generations. But he repays those who hate him to their face and destroys them. He will not be slow to deal with someone who hates him; he will repay him to his face. Therefore, you are to keep the mitzvot, laws and rulings which I am giving you today, and obey them.
