Moses says this is the covenant the Lord commanded him to make with the Israelites in Moab, in addition to the covenant at Horeb. He reminds them of what they have seen: the signs and wonders in Egypt, and how during forty years in the wilderness their clothes and sandals did not wear out, and they ate no bread and drank no wine, so that they would know the Lord is their God. He also recalls how they defeated Sihon and Og and took their land, which they gave to Reuben, Gad and the half-tribe of Manasseh. He asks them to keep the words of the covenant so that they may prosper.
Today all stand before the Lord, leaders, elders, officials, men, children, wives and the foreigner in the camp, to enter into the covenant and its oath. Not only they, but also those who are not here today, that is, future generations. Moses reminds them how they lived in Egypt and among the nations, and he sees the idols of wood, stone, silver and gold among them.
He warns that there be no man, woman, family or tribe whose heart turns away from the Lord to serve other gods, a root bearing poison and bitterness. Whoever hears the words of the curse and blesses himself in his heart, thinking he will have peace even while walking in stubbornness, will not be spared. The Lord's anger will smolder against him. The land will be desolate, like Sodom and Gomorrah, Admah and Zeboiim, and the nations will ask why the Lord did this. The answer will be that they abandoned the covenant of the Lord. The chapter ends with the statement that the secret things belong to the Lord and the revealed things to us and our children forever, so that we may keep the words of this law.
