Deuteronomy 11:15

13It shall happen, if you shall listen diligently to my commandments which I command you today, to love the LORD your God, and to serve him with all your heart and with all your soul,

14that I will give the rain for your land in its season, the early rain and the latter rain, that you may gather in your grain, your new wine, and your oil.

15I will give grass in your fields for your livestock, and you shall eat and be full.

16Be careful, lest your heart be deceived, and you turn away to serve other gods and worship them;

17and the LORD’s anger be kindled against you, and he shut up the sky so that there is no rain, and the land doesn’t yield its fruit; and you perish quickly from off the good land which the LORD gives you.
