8 Therefore shall ye keep all the commandment which I command thee this day, that ye may be strong, and go in and possess the land, whither ye go over to possess it; 9 and that ye may prolong your days in the land, which Jehovah sware unto your fathers to give unto them and to their seed, a land flowing with milk and honey. 10 For the land, whither thou goest 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, whither ye go over to possess it, is a land of hills and valleys, [and] drinketh water of the rain of heaven, 12 a land which Jehovah thy God careth for: the eyes of Jehovah thy God are always upon it, from the beginning of the year even unto the end of the year. 13 And it shall come to pass, if ye shall hearken diligently unto my commandments which I command you this day, to love Jehovah your God, and to serve him with all your heart and with all your soul, 14 that I will give the rain of your land in its season, the former rain and the latter rain, that thou mayest gather in thy grain, and thy new wine, and thine oil. 15 And I will give grass in thy fields for thy cattle, and thou shalt eat and be full. 16 Take heed to yourselves, lest your heart be deceived, and ye turn aside, and serve other gods, and worship them; 17 and the anger of Jehovah be kindled against you, and he shut up the heavens, so that there shall be no rain, and the land shall not yield its fruit; and ye perish quickly from off the good land which Jehovah giveth you.

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.
