Deuteronomy 6:3-7

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.

These words, which I am commanding you today, shall be on your heart.

And you shall repeat them diligently to your sons and speak of them when you sit in your house, when you walk on the road, when you lie down, and when you get up.
