Deuteronomy 11:16

It shall happen, if you shall listen diligently to my commandments which I command you today, to love the LORD your God, and to serve him with all your heart and with all your soul,

that 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.

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

and the LORD’s anger be kindled against you, and he shut up the sky so that there is no rain, and the land doesn’t yield its fruit; and you perish quickly from off the good land which the LORD gives you.

Therefore you shall lay up these words of mine in your heart and in your soul. You shall bind them for a sign on your hand, and they shall be for frontlets between your eyes.

You shall teach them to your children, talking of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up.
