Deuteronomy 11:10-17

10For the land that you are entering to take possession of it is not like the land of Egypt, from which you have come, where you sowed your seed and irrigated it, like a garden of vegetables.

11But the land that you are going over to possess is a land of hills and valleys, which drinks water by the rain from heaven,

12a land that the Lord your God cares for. The eyes of the Lord your God are always upon it, from the beginning of the year to the end of the year.

13"And if you will indeed obey my commandments that I command you today, to love the Lord your God, and to serve him with all your heart and with all your soul,

14he will give the rain for your land in its season, the early rain and the later rain, that you may gather in your grain and your wine and your oil.

15And he will give grass in your fields for your livestock, and you shall eat and be full.

16Take care lest your heart be deceived, and you turn aside and serve other gods and worship them;

17then the anger of the Lord will be kindled against you, and he will shut up the heavens, so that there will be no rain, and the land will yield no fruit, and you will perish quickly off the good land that the Lord is giving you.
