13 'And it shall be that if you earnestly obey My commandments which I command you today, to love the Lord your God and serve Him with all your heart and with all your soul, 14 then I will give you the rain for your land in its season, the early rain and the latter rain, that you may gather in your grain, your new wine, and your oil. 15 And I will send grass in your fields for your livestock, that you may eat and be filled.' 16 Take heed to yourselves, lest your heart be deceived, and you turn aside and serve other gods and worship them, 17 lest the Lord's anger be aroused against you, and He shut up the heavens so that there be no rain, and the land yield no produce, and you perish quickly from the good land which the Lord is giving you.
18 "Therefore you shall lay up these words of mine in your heart and in your soul, and bind them as a sign on your hand, and they shall be as frontlets between your eyes. 19 You shall teach them to your children, speaking of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up. 20 And you shall write them on the doorposts of your house and on your gates, 21 that your days and the days of your children may be multiplied in the land of which the Lord swore to your fathers to give them, like the days of the heavens above 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.
