Deuteronomy 6:1-5

“Now this is the commandment, the statutes, and the judgments which the Lord your God has commanded me to teach you, so that you may do them in the land where you are going over to take possession of it,

so that you, your son, and your grandson will fear the Lord your God, to keep all His statutes and His commandments which I command you, all the days of your life, and that your days may be prolonged.

Now Israel, you shall listen and be careful to do them, so that it may go well for you and that you may increase greatly, just as the Lord, the God of your fathers, has promised you, in a land flowing with milk and honey.

“Hear, Israel! The Lord is our God, the Lord is one!

And you shall love the Lord your God with all your heart and with all your soul and with all your strength.
