Deuteronomy 11:10-15

For the land which you go to possess is not like the land of Egypt from which you have come, where you sowed your seed and watered it by foot, as a vegetable garden; but the land which you cross over to possess is a land of hills and valleys, which drinks water from the rain of heaven, a land for which the LORD your God cares; the eyes of the LORD your God are always on it, from the beginning of the year to the very end of the year. ‘And it shall be that if you earnestly obey My commandments which I command you today, to love the LORD your God and serve Him with all your heart and with all your soul, then I will give you 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 send grass in your fields for your livestock, that you may eat and be filled.’
