Deuteronomy 6:5

2 So that living in the fear of the Lord your God, you may keep all his laws and his orders, which I give you: you and your son and your son's son, all the days of your life; and so that your life may be long.

3 So give ear, O Israel, and take care to do this; so that it may be well for you, and you may be greatly increased, as the Lord the God of your fathers has given you his word, in a land flowing with milk and honey.

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;
