Deuteronomy 6:4-9

4 "Hear, O Israel: 1The LORD our God, the LORD is one.a
5 You 2shall love the LORD your God with all your heart and with all your soul and with all your might.
6 And 3these words that I command you today shall be on your heart.
7 4You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise.
8 5You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes.
9 6You shall write them on the doorposts of your house and on your gates.
