13 And it will be that if you truly give ear to the orders which I put before you this day, loving the Lord your God and worshipping him with all your heart and all your soul, 14 Then I will send rain on your land at the right time, the early rains and the late rains, so that you may get in your grain and your wine and your oil. 15 And I will give grass in your fields for your cattle, so that you may have food in full measure. 16 But take care that your hearts are not turned to false ways so that you become servants and worshippers of other gods; 17 For if you do so, the wrath of the Lord will be burning against you, and the heaven will be shut up so that there is no rain and the land will give no fruit; and in a very little time you will be cut off from the good land which the Lord is giving you.
18 So keep these words deep in your heart and in your soul, and have them fixed on your hand for a sign and marked on your brow; 19 Teaching them to your children, and talking of them when you are at rest in your house or walking by the way, when you go to sleep and when you get up: 20 Writing them on the pillars of your houses and over the doors of your towns: 21 So that your days, and the days of your children, may be long in the land which the Lord by his oath to your fathers said he would give them, like the days of the eternal heavens.
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.
