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:
Keil & Delitzsch
By this was Israel to know that Jehovah their God was the true God, the faithful God, who keeps His covenant, showing mercy to those who love Him, even to the thousandth generation, but repaying those who hate Him to the face. This development of the nature of God Moses introduces from Exo 20:5-6, as a light warning not to forfeit the mercy of God, or draw upon themselves His holy wrath by falling into idolatry. To this end He emphatically carries out still further the thought of retribution, by adding להאבידו, "to destroy him" (the hater), and וגו יאהר לא, "He delays not to His hater (sc., to repay him); He will repay him to his face." "To the face of every one of them," i.e., that they may see and feel that they are smitten by God (Rosenmller).
