13 From now on if you listen obediently to the commandments that I am commanding you today, love God, your God, and serve him with everything you have within you, 14 he'll take charge of sending the rain at the right time, both autumn and spring rains, so that you'll be able to harvest your grain, your grapes, your olives. 15 He'll make sure there's plenty of grass for your animals. You'll have plenty to eat. 16 But be vigilant, lest you be seduced away and end up serving and worshiping other gods 17 and God erupts in anger and shuts down Heaven so there's no rain and nothing grows in the fields, and in no time at all you're starved out - not a trace of you left on the good land that God is giving you.

18 Place these words on your hearts. Get them deep inside you. Tie them on your hands and foreheads as a reminder. 19 Teach them to your children. Talk about them wherever you are, sitting at home or walking in the street; talk about them from the time you get up in the morning until you fall into bed at night. 20 Inscribe them on the doorposts and gates of your cities 21 so that you'll live a long time, and your children with you, on the soil that God promised to give your ancestors for as long as there is a sky over the Earth.

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.

Commentary on Deuteronomy 11:18-25

(Read Deuteronomy 11:18-25)

Let all be directed by the three rules here given. 1. Let our hearts be filled with the word of God. There will not be good practices in the life, unless there be good thoughts, good affections, and good principles in the heart. 2. Let our eyes be fixed upon the word of God, having constant regard to it as the guide of our way, as the rule of our work, Psalm 119:30. 3. Let our tongues be employed about the word of God. Nor will any thing do more to cause prosperity, and keeping up religion in a nation, than the good education of children.
