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 It was not because you were more in number than any other people that the LORD set his love upon you and chose you, for you were the fewest of all peoples;

8 but it is because the LORD loves you, and is keeping the oath which he swore to your fathers, that the LORD has brought you out with a mighty hand, and redeemed you from the house of bondage, from the hand of Pharaoh king of Egypt.

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

10 and requites to their face those who hate him, by destroying them; he will not be slack with him who hates him, he will requite him to his face.

11 You shall therefore be careful to do the commandment, and the statutes, and the ordinances, which I command you this day.
