Deuteronomy 11:13-17

“It shall come about, if you listen obediently to my commandments which I am commanding you today, to love the LORD your God and to serve Him with all your heart and all your soul, that He will give the rain for your land in its season, the early and late rain, that you may gather in your grain and your new wine and your oil. He will give grass in your fields for your cattle, and you will eat and be satisfied. Beware that your hearts are not deceived, and that you do not turn away and serve other gods and worship them. Or the anger of the LORD will be kindled against you, and He will shut up the heavens so that there will be no rain and the ground will not yield its fruit; and you will perish quickly from the good land which the LORD is giving you.
