“Now these are the commandments, statutes, and ordinances that the LORD your God instructed me to teach you so that you may carry them out in the land where you are headed and that you may so revere the LORD your God that you will keep all his statutes and commandments that I am giving you – you, your children, and your grandchildren – all your lives, to prolong your days. Pay attention, Israel, and be careful to do this so that it may go well with you and that you may increase greatly in number – as the LORD, God of your ancestors, said to you, you will have a land flowing with milk and honey. Listen, Israel: The LORD is our God, the LORD is one! You must love the LORD your God with your whole mind, your whole being, and all your strength. These words I am commanding you today must be kept in mind, and you must teach them to your children and speak of them as you sit in your house, as you walk along the road, as you lie down, and as you get up. You should tie them as a reminder on your forearm and fasten them as symbols on your forehead. Inscribe them on the doorframes of your houses and gates.”

“Now one of the experts in the law came and heard them debating. When he saw that Jesus answered them well, he asked him, “Which commandment is the most important of all?” Jesus answered, “The most important is: ‘ Listen, Israel, the Lord our God, the Lord is one. Love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.’ The second is: ‘ Love your neighbor as yourself.’ There is no other commandment greater than these.””
