8 Therefore you shall keep all the commandment which I command you this day, that you may be strong, and go in and possess the land, where you go over to possess it; 9 and that you may prolong your days in the land, which Yahweh swore to your fathers to give to them and to their seed, a land flowing with milk and honey. 10 For the land, where you go in to possess it, isn’t as the land of Egypt, from whence you came out, where you sowed your seed, and watered it with your foot, as a garden of herbs; 11 but the land, where you go over to possess it, is a land of hills and valleys, and drinks water of the rain of the sky, 12 a land which Yahweh your God cares for: the eyes of Yahweh your God are always on it, from the beginning of the year even to the end of the year.
Matthew Henry's Commentary on Deuteronomy 11:8-12
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.
