Deuteronomy 11:16-18

Revised Standard Version

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.
