Deuteronomy 7:9-11

Douay-Rheims 1899 American Edition

⁹ And thou shalt know that the Lord thy God, he is a strong and faithful God, keeping his covenant and mercy to them that love him, and to them that keep his commandments, unto a thousand generations:

¹⁰ And repaying forthwith them that hate him, so as to destroy them, without further delay immediately rendering to them what they deserve.

¹¹ Keep therefore the precepts and ceremonies and judgments, which I command thee this day to do.
