Deuteronomy 11:8-17

So obey all the commands I am giving you today so that you will be strong and can go in and take the land you are going to take as your own. Then you will live a long time in the land that the LORD promised to give to your ancestors and their descendants, a fertile land. The land you are going to take is not like Egypt, where you were. There you had to plant your seed and water it, like a vegetable garden, by using your feet. But the land that you will soon cross the Jordan River to take is a land of hills and valleys, a land that drinks rain from heaven. It is a land the LORD your God cares for. His eyes are on it continually, and he watches it from the beginning of the year to the end. If you carefully obey the commands I am giving you today and love the LORD your God and serve him with your whole being, then he will send rain on your land at the right time, in the fall and spring, and you will be able to gather your grain, new wine, and oil. He will put grass in the fields for your cattle, and you will have plenty to eat. Be careful, or you will be fooled and will turn away to serve and worship other gods. If you do, the LORD will become angry with you and will shut the heavens so it will not rain. Then the land will not grow crops, and you will soon die in the good land the LORD is giving you.
