Deuteronomy 11:16-18

King James Version

¹⁶ Take heed to yourselves, that your heart be not deceived, and ye turn aside, and serve other gods, and worship them;

¹⁷ And then the Lord's wrath be kindled against you, and he shut up the heaven, that there be no rain, and that the land yield not her fruit; and lest ye perish quickly from off the good land which the Lord giveth you.

¹⁸ Therefore shall ye lay up these my words in your heart and in your soul, and bind them for a sign upon your hand, that they may be as frontlets between your eyes.
