8 So it's you who are in charge of keeping the entire commandment that I command you today so that you'll have the strength to invade and possess the land that you are crossing the river to make your own. 9 Your obedience will give you a long life on the soil that God promised to give your ancestors and their children, a land flowing with milk and honey. 10 The land you are entering to take up ownership isn't like Egypt, the land you left, where you had to plant your own seed and water it yourselves as in a vegetable garden. 11 But the land you are about to cross the river and take for your own is a land of mountains and valleys; it drinks water that rains from the sky. 12 It's a land that God, your God, personally tends - he's the gardener - he alone keeps his eye on it all year long.

Commentary on Deuteronomy 11:8-17
(Read Deuteronomy 11:8-17)
Moses sets before them, for the future, life and death, the blessing and the curse, according as they did or did not keep God's commandment. Sin tends to shorten the days of all men, and to shorten the days of a people's prosperity. God will bless them with an abundance of all good things, if they would love him and serve him. Godliness has the promise of the life that now is; but the favour of God shall put gladness into the heart, more than the increase of corn, and wine, and oil. Revolt from God to idols would certainly be their ruin. Take heed that your hearts be not deceived. All who forsake God to set their affection upon any creature, will find themselves wretchedly deceived, to their own destruction; and this will make it worse, that it was for want of taking heed.
