Deuteronomy 6:1-6

1These are the commands, decrees and laws the Lord your God directed me to teach you to observe in the land that you are crossing the Jordan to possess, 2so that you, your children and their children after them may fear the Lord your God as long as you live by keeping all his decrees and commands that I give you, and so that you may enjoy long life. 3Hear, Israel, and be careful to obey so that it may go well with you and that you may increase greatly in a land flowing with milk and honey, just as the Lord, the God of your ancestors, promised you. 4Hear, O Israel: The Lord our God, the Lord is one. 5Love the Lord your God with all your heart and with all your soul and with all your strength. 6These commandments that I give you today are to be on your hearts.
