Deuteronomy 7:9

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 you surpass all nations in number, is the Lord joined unto you, and hath chosen you, for you are the fewest of any people:

8 But because the Lord hath loved you, and hath kept his oath, which he swore to your fathers: and hath brought you out with a strong hand, and redeemed you from the house of bondage, out of the hand of Pharao the king of Egypt.

9 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:

10 And repaying forthwith them that hate him, so as to destroy them, without further delay immediately rendering to them what they deserve.

11 Keep therefore the precepts and ceremonies and judgments, which I command thee this day to do.
