Deuteronomy 11:13-19Revised Standard Version (RSV)
13 “And if you will obey my commandments which I command you this day, to love the Lord your God, and to serve him with all your heart and with all your soul, 14 he[a] 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. 15 And he[b] will give grass in your fields for your cattle, and you shall eat and be full. 16 Take heed lest your heart be deceived, and you turn aside and serve other gods and worship them, 17 and the anger of the Lord be kindled against you, and he shut up the heavens, so that there be no rain, and the land yield no fruit, and you perish quickly off the good land which the Lord gives you.
18 “You shall therefore lay up these words of mine in your heart and in your soul; and you shall bind them as a sign upon your hand, and they shall be as frontlets between your eyes. 19 And you shall teach them to your children, talking of them when you are sitting in your house, and when you are walking by the way, and when you lie down, and when you rise.
