Deuteronomy 11:8-15

Observe therefore all the commands I am giving you today, so that you may have the strength to go in and take over the land that you are crossing the Jordan to possess, and so that you may live long in the land the LORD swore to your ancestors to give to them and their descendants, a land flowing with milk and honey. The land you are entering to take over is not like the land of Egypt, from which you have come, where you planted your seed and irrigated it by foot as in a vegetable garden. But the land you are crossing the Jordan to take possession of is a land of mountains and valleys that drinks rain from heaven. It is a land the LORD your God cares for; the eyes of the LORD your God are continually on it from the beginning of the year to its end. 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.
