11 Rather, the land you will soon take over is a land of hills and valleys with plenty of rain- 12 a land that the Lord your God cares for. He watches over it through each season of the year! 13 "If you carefully obey the commands I am giving you today, and if you love the Lord your God and serve him with all your heart and soul, 14 then he will send the rains in their proper seasons-the early and late rains-so you can bring in your harvests of grain, new wine, and olive oil. 15 He will give you lush pastureland for your livestock, and you yourselves will have all you want to eat. 16 "But be careful. Don't let your heart be deceived so that you turn away from the Lord and serve and worship other gods.

Matthew Henry's Commentary on Deuteronomy 11:11-16

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.
