3 Understand therefore this day, that the Lord thy God is he which goeth over before thee; as a consuming fire he shall destroy them, and he shall bring them down before thy face: so shalt thou drive them out, and destroy them quickly, as the Lord hath said unto thee.
3 But be assured today that the Lord your God is the one who goes across ahead of you like a devouring fire. He will destroy them; he will subdue them before you. And you will drive them out and annihilate them quickly, as the Lord has promised you.
3 Know therefore today that he who goes over before you as a consuming fire is the Lord your God. He will destroy them and subdue them before you. So you shall drive them out and make them perish quickly, as the Lord has promised you.
3 Today know this: God, your God, is crossing the river ahead of you - he's a consuming fire. He will destroy the nations, he will put them under your power. You will dispossess them and very quickly wipe them out, just as God promised you would.
3 Therefore understand today that the Lord your God is He who goes over before you as a consuming fire. He will destroy them and bring them down before you; so you shall drive them out and destroy them quickly, as the Lord has said to you.
3 But recognize today that the Lord your God is the one who will cross over ahead of you like a devouring fire to destroy them. He will subdue them so that you will quickly conquer them and drive them out, just as the Lord has promised.
Matthew Henry's Commentary on Deuteronomy 9:3
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.
