Deuteronomy 11:8-17

So you must keep every commandment I am giving you today That way you will have the strength to enter and take over the country that you are crossing the Jordan to have as your own, You will also have long lives in the country that the Lord promised to give your forefathers and their descendants, a land flowing with milk and honey. The country you're entering to occupy isn't like the country of Egypt that you've come from. There you had to sow your seed and work hard irrigating the ground, like taking care of a vegetable garden. But here in the country that you are crossing the Jordan to take over is a land of mountains and valleys that receives plenty of rain It is a land that the Lord your God takes care of. The Lord your God is always watching over it, all year long. So if you pay careful attention to keep the commandments that I'm giving to you today, if you love the Lord your God and worship him with all your mind and with all your being, then I will send rain for your land at the right time, rain in autumn and spring, so that you can harvest your grain, new wine, and olive oil. I will also provide grass in the fields for your livestock. You will have more than enough to eat. But make sure that you're not fooled into worshiping and bowing down to other gods, or the Lord will become angry with you. He won't send any rain, and the land won't produce any crops, and you will soon die, even in the good land that the Lord is giving you.
