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 The LORD did not set His affection on you and choose you because you were more numerous than the other peoples, for you were the fewest of all peoples.

8 But because the LORD loved you and kept the oath He swore to your fathers, He brought you out with a mighty hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt.

9 Know therefore that the LORD your God is God, the faithful God who keeps His covenant of loving devotion for a thousand generations of those who love Him and keep His commandments.

10 But those who hate Him He repays to their faces with destruction; He will not hesitate to repay to his face the one who hates Him.

11 So keep the commandments and statutes and ordinances that I am giving you to follow this day.
