Therefore, you shall love the Lord, your God, with all your heart, and with all your soul, and with all your strength.  Take to heart these words which I enjoin on you today.  Drill them into your children.  Speak of them at home and abroad, whether you are busy or at rest.  Bind them at your wrist as a sign and let them be as a pendant on your forehead.  Write them on the doorposts of your houses and on your gates.
