Mark 12:28-31
28 One of the Sofrim came, and heard them questioning together. Knowing that he had answered them well, asked him, “What mitzvah is the greatest of all?”
29 Yeshua answered, “The greatest is, ‘Hear, Yisra’el, the Lord our God, the Lord is one:
30 you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.’ This is the primary mitzvah.
31 The second is like this, ‘You shall love your neighbor as yourself.’ There is no other mitzvah greater than these.” HNV
