New Defender's Study Bible Notes
9:2 children of Anak. See note on Numbers 13:33.
9:5 the wickedness of these nations. The Canaanite nations that had inhabited the land for many centuries were indeed paragons of wickedness, not only pagan idolaters, but practitioners of every form of sexual debauchery, as well as extreme cruelties, even offering their own children in fiery sacrifices to their demonic nature gods (Deuteronomy 12:31). God had given them many centuries in which to repent and turn back to God (note Genesis 15:16), but they had only grown worse, and the only remedy was destruction before they could contaminate the world.
9:10 the finger of God. The fact that the ten commandments were written on stone by God Himself is stressed no less than seven times (Exodus 31:18; 32:15; 34:1; 34:28; Deuteronomy 4:13; 9:10; 10:4). This is an indication of the importance placed by God on these stone-inscribed words.
