Deuteronomy 11:15-18 New King James Version (NKJV)

15. And I will send grass in your fields for your livestock, that you may eat and be filled.’

16. “Take heed to yourselves, lest your heart be deceived, and you turn aside and serve other gods and worship them,

17. lest the Lord’s anger be aroused against you, and He shut up the heavens so that there be no rain, and the land yield no produce, and you perish quickly from the good land which the Lord is giving you.

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