8 Keep then all the commandment which I command you this day, that ye may be strong, and enter in and possess the land, whither ye pass over to possess it; 9 and that ye may prolong your days in the land which Jehovah swore unto your fathers to give unto them and unto their seed, a land flowing with milk and honey. 10 For the land, whither thou enterest in to possess it, is not as the land of Egypt, from whence ye came out, where thou sowedst thy seed, and wateredst it with thy foot, as a garden of herbs; 11 but the land, whereunto ye are passing over to possess it, is a land of mountains and valleys, which drinketh water of the rain of heaven, 12 a land which Jehovah thy God careth for; the eyes of Jehovah thy God are constantly upon it, from the beginning of the year even unto 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.
