Deuteronomy 7:9

9 Know now then that the LORD your God is the only true God! He is the faithful God, who keeps the covenant and proves loyal to everyone who loves him and keeps his commands—even to the thousandth generation!

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 greater than all other people that the LORD loved you and chose you. In fact, you were the smallest of peoples!

8 No, it is because the LORD loved you and because he kept the solemn pledge he swore to your ancestors that the LORD brought you out with a strong hand and saved you from the house of slavery, from the power of Pharaoh, Egypt's king.

9 Know now then that the LORD your God is the only true God! He is the faithful God, who keeps the covenant and proves loyal to everyone who loves him and keeps his commands—even to the thousandth generation!

10 He is the God who personally repays anyone who hates him, ultimately destroying that kind of person. The LORD does not waste time with anyone who hates him; he repays them personally.

11 So make sure you carefully keep the commandment, the regulations, and the case laws that I am commanding you right now.
