Deuteronomy 7:9-11

Young's Literal Translation

⁹ `And thou hast known that Jehovah thy God He [is] God, the faithful God, keeping the covenant, and the kindness, to those loving Him, and to those keeping His commands -- to a thousand generations,

¹⁰ and repaying to those hating Him, unto their face, to destroy them; He delayeth not to him who is hating Him -- unto his face, He repayeth to him --

¹¹ and thou hast kept the command, and the statutes, and the judgments, which I am commanding thee to-day to do them.
