Deuteronomy 11:13-21

13So if you faithfully obey the commands I am giving you today—to love the LORD your God and to serve him with all your heart and with all your soul— 14then I will send rain on your land in its season, both autumn and spring rains, so that you may gather in your grain, new wine and olive oil.

15I will provide grass in the fields for your cattle, and you will eat and be satisfied. 16Be careful, or you will be enticed to turn away and worship other gods and bow down to them. 17Then the LORD ’s anger will burn against you, and he will shut up the heavens so that it will not rain and the ground will yield no produce, and you will soon perish from the good land the LORD is giving you. 18Fix these words of mine in your hearts and minds; tie them as symbols on your hands and bind them on your foreheads. 19Teach them to your children, talking about them when you sit at home and when you walk along the road, when you lie down and when you get up. 20Write them on the doorframes of your houses and on your gates,

21so that your days and the days of your children may be many in the land the LORD swore to give your ancestors, as many as the days that the heavens are above the earth.
