Deuteronomy 7:9 Meaning and Commentary

Ver. 9 Know therefore that the Lord thy God, he is God
The only true and living God, and not the idols of the Gentiles, who are false and lifeless ones, and therefore not the proper objects of adoration:

the faithful God, which keepeth covenant and mercy;
as appeared by fulfilling the promise made to their fathers, in bringing them out of Egypt, and now them to the borders of the land of Canaan given them for an inheritance:

with them that love him, and keep his commandments, to a thousand
generations;
see ( Exodus 20:6 ) which are not the causes or conditions of his covenant and mercy, nor of his keeping them, but descriptive of the persons that enjoy the benefit thereof.

Deuteronomy 7:9 In-Context

7 Not because ye were more than the other peoples has the LORD desired you and chosen you; for ye were the fewest of all the peoples;

8 but because the LORD loved you and because he would keep the oath which he had sworn unto your fathers, has the LORD brought you out with a mighty hand and ransomed you out of the house of slavery from the hand of Pharaoh, king of Egypt.

9 Know, therefore, that the LORD thy God, he is God, the faithful God, who keeps covenant and mercy with those that love him and keep his commandments to a thousand generations

10 and repays him that hates him to his face, to destroy him; he will not be slack to him that hates him; he will repay him to his face.

11 Keep, therefore, the commandments and statutes and rights, which I command thee this day, to do them.
