Deuteronomy 6:2-5

and you and your children and grandchildren must fear the LORD your God as long as you live. If you obey all his decrees and commands, you will enjoy a long life. Listen closely, Israel, and be careful to obey. Then all will go well with you, and you will have many children in the land flowing with milk and honey, just as the LORD, the God of your ancestors, promised you. “Listen, O Israel! The LORD is our God, the LORD alone. And you must love the LORD your God with all your heart, all your soul, and all your strength.
