Deuteronomy 11:13-17

So if you faithfully obey the commands I am giving you today—to love the LORD your God and to serve him with all your heart and with all your soul— then I will send rain on your land in its season, both autumn and spring rains, so that you may gather in your grain, new wine and olive oil. I will provide grass in the fields for your cattle, and you will eat and be satisfied. Be careful, or you will be enticed to turn away and worship other gods and bow down to them. Then the LORD’s anger will burn against you, and he will shut up the heavens so that it will not rain and the ground will yield no produce, and you will soon perish from the good land the LORD is giving you.
