4 Give ear, O Israel: the Lord our God is one Lord:

5 And the Lord your God is to be loved with all your heart and with all your soul and with all your strength.

6 Keep these words, which I say to you this day, deep in your hearts;

7 Teaching them to your children with all care, talking of them when you are at rest in your house or walking by the way, when you go to sleep and when you get up.

8 Let them be fixed as a sign on your hand, and marked on your brow;

9 Have them lettered on the pillars of your houses and over the doors of your towns.

Deuteronômio 6:4-9
