13 If you will only heed his every commandment that I am commanding you today-loving the Lord your God, and serving him with all your heart and with all your soul- 14 then he will give the rain for your land in its season, the early rain and the later rain, and you will gather in your grain, your wine, and your oil; 15 and he will give grass in your fields for your livestock, and you will eat your fill. 16 Take care, or you will be seduced into turning away, serving other gods and worshiping them, 17 for then the anger of the Lord will be kindled against you and he will shut up the heavens, so that there will be no rain and the land will yield no fruit; then you will perish quickly off the good land that the Lord is giving you.
18 You shall put these words of mine in your heart and soul, and you shall bind them as a sign on your hand, and fix them as an emblem on your forehead. 19 Teach them to your children, talking about them when you are at home and when you are away, when you lie down and when you rise. 20 Write them on the doorposts of your house and on your gates, 21 so that your days and the days of your children may be multiplied in the land that the Lord swore to your ancestors to give them, as long as the heavens are above the earth.
Matthew Henry's Commentary on Deuteronomy 11:13-21
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.
