“You shall therefore lay up
these words of mine in your heart and in your soul, and you shall bind them as
a sign on your hand, and they shall be as frontlets between your eyes. 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. You shall write them on the
doorposts of your house and on your gates…” Deuteronomy 11: 18-20
