Bible Notes Online - Deuteronomy 9 - ESV
Commentary

v1-6: The Lord had laid down instructions for the people, "when the Lord your God brings you into the land" (7.1, and many similar references). The people had to be mindful of these things, so that they would live in obedience to God.

v1-3: The people were about to cross over into Canaan. The land had been visited by twelve spies, and Moses referred to their report (Num 13.28,33). Although ten of the spies had said that the enemy was too powerful, God had promised victory, so that had to happen; He would destroy them and subdue them. The Israelites could not leave it all to God, they had to drive them out and annihilate them. These verses demonstrate the balance between God’s work and ours.

v4-6: The Israelites were not to be proud; the destruction of the Canaanite peoples was because of their wickedness, and because of God's promises to Abraham, Isaac, and Jacob. The people were not being rewarded for their righteousness, for they were a stiff-necked people.

v7-29: As if to convince the people, Moses reminded them of their rebellion. He referred to specific incidents (v8,22,23), and he said that they were always rebellious (v7,24). He did not refer to the punishments inflicted upon the people, for his purpose was simply to remind them of their rebellious attitudes.

Moses also reminded the people of his actions on their behalf, as he interceded for them; v18-21; 25-29. See Num 14.13-16.

Such attitudes can rise in our own lives, informing our thinking, and influencing others, damaging our ministry, and robbing us of blessing. As in ch 9, we should be mindful of God's things, and cultivate our relationship with Him.
