Mark 12:31-33

31This is the second: ‘You shall [unselfishly] love your neighbor as yourself.’ There is no other commandment greater than these.”

32The scribe said to Him, “Admirably answered, Teacher; You truthfully stated that He is One, and there is no other but Him;

33and to love Him with all the heart and with all the understanding and with all the strength, and to [unselfishly] love one’s neighbor as oneself, is much more than all burnt offerings and sacrifices.”
