Moses calls the people to love the Lord their God and always keep his commands. He reminds them that the children present did not see the Lord's discipline, but their own eyes have seen the signs in Egypt, the crossing of the Red Sea and what happened in the wilderness, including the earth opening and swallowing Dathan and Abiram.
Then he describes the land they are about to possess. It is not like Egypt, where it was watered with effort, but a land of hills and valleys that drinks rain from heaven and that the Lord cares for from the beginning of the year to its end. If they obey, he will send the rain in its season, and if they turn to other gods, he will shut up the heavens and they will lose the good land.
Moses commands them to put these words in heart and soul, tie them as a sign on the hand, set them between the eyes, teach them to their children and write them on the doorposts of their houses and on their gates. If they keep them, the Lord will drive out the nations and no one will be able to stand against them. The chapter ends by setting before them a blessing and a curse: blessing if they obey and curse if they turn away. When they enter the land, the blessing will be proclaimed on Mount Gerizim and the curse on Mount Ebal.
