Deuteronomy 6:2-6

that you may fear the LORD your God, to keep all His statutes and His commandments which I command you, you and your son and your grandson, all the days of your life, and that your days may be prolonged. Therefore hear, O Israel, and be careful to observe it, that it may be well with you, and that you may multiply greatly as the LORD God of your fathers has promised you—‘a land flowing with milk and honey.’ “Hear, O Israel: The LORD our God, the LORD is one! You shall love the LORD your God with all your heart, with all your soul, and with all your strength. “And these words which I command you today shall be in your heart.
