Deuteronomy 6:4-9

4Listen, Israel: The Lord is our God, the Lord is one!

5You must love the Lord your God with your whole mind, your whole being, and all your strength.

6These words I am commanding you today must be kept in mind,

7and you must teach them to your children and speak of them as you sit in your house, as you walk along the road, as you lie down, and as you get up.

8You should tie them as a reminder on your forearm and fasten them as symbols on your forehead.

9Inscribe them on the doorframes of your houses and gates.
