Deuteronomy 7:9

9 `And thou hast known that Jehovah thy God He [is] God, the faithful God, keeping the covenant, and the kindness, to those loving Him, and to those keeping His commands -- to a thousand generations,

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 of your being more numerous than any of the peoples hath Jehovah delighted in you, and fixeth on you, for ye [are] the least of all the peoples,
8 but because of Jehovah's loving you, and because of His keeping the oath which He hath sworn to your fathers, hath Jehovah brought you out by a strong hand, and doth ransom you from a house of servants, from the hand of Pharaoh king of Egypt.
9 `And thou hast known that Jehovah thy God He [is] God, the faithful God, keeping the covenant, and the kindness, to those loving Him, and to those keeping His commands -- to a thousand generations,
10 and repaying to those hating Him, unto their face, to destroy them; He delayeth not to him who is hating Him -- unto his face, He repayeth to him --
11 and thou hast kept the command, and the statutes, and the judgments, which I am commanding thee to-day to do them.
