Deuteronomy 11:8-17

Therefore you shall keep all the commandments which I command you today, that you may be strong and go in and possess the land which you go across [the Jordan] to possess, And that you may live long in the land which the Lord swore to your fathers to give to them and to their descendants, a land flowing with milk and honey. For the land which you go in to possess is not like the land of Egypt, from which you came out, where you sowed your seed and watered it with your foot laboriously as in a garden of vegetables. But the land which you enter to possess is a land of hills and valleys which drinks water of the rain of the heavens, A land for which the Lord your God cares; the eyes of the Lord your God are always upon it from the beginning of the year to the end of the year. And if you will diligently heed My commandments which I command you this day–to love the Lord your God and to serve Him with all your [mind and] heart and with your entire being– 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. And I will give grass in your fields for your cattle, that you may eat and be full. Take heed to yourselves, lest your [minds and] hearts be deceived and you turn aside and serve other gods and worship them, And the Lord's anger be kindled against you, and He shut up the heavens so that there will be no rain and the land will not yield its fruit, and you perish quickly off the good land which the Lord gives you.
