6 Understand therefore, that the Lord thy God giveth thee not this good land to possess it for thy righteousness; for thou art a stiffnecked people.
6 Understand, then, that it is not because of your righteousness that the Lord your God is giving you this good land to possess, for you are a stiff-necked people.
6 "Know, therefore, that the Lord your God is not giving you this good land to possess because of your righteousness, for you are a stubborn people.
6 Know this and don't ever forget it: It's not because of any good that you've done that God is giving you this good land to own. Anything but! You're stubborn as mules.
6 Therefore understand that the Lord your God is not giving you this good land to possess because of your righteousness, for you are a stiff-necked people.
6 You must recognize that the Lord your God is not giving you this good land because you are good, for you are not-you are a stubborn people.
Matthew Henry's Commentary on Deuteronomy 9:6
Commentary on Deuteronomy 9:1-6
(Read Deuteronomy 9:1-6)
Moses represents the strength of the enemies they were now to encounter. This was to drive them to God, and engage their hope in him. He assures them of victory, by the presence of God with them. He cautions them not to have the least thought of their own righteousness, as if that procured this favour at God's hand. In Christ we have both righteousness and strength; in Him we must glory, not in ourselves, nor in any sufficiency of our own. It is for the wickedness of these nations that God drives them out. All whom God rejects, are rejected for their own wickedness; but none whom he accepts are accepted for their own righteousness. Thus boasting is for ever done away: see Ephesians 2:9,11,12.
