Matthew 22:34-40 But when the Pharisees heard that he had silenced the Sadducees, they gathered together. (35) And one of them, a lawyer, asked him a question to test him. (36) “Teacher, which is the great commandment in the Law?” (37) And he said to him, “You shall love the Lord your God with all your heart and with all your soul and with all your mind. (38) This is the great and first commandment. (39) And a second is like it: You shall love your neighbor as yourself. (40) On these two commandments depend all the Law and the Prophets.”
Mark 12:28-34 And one of the scribes came up and heard them disputing with one another, and seeing that he answered them well, asked him, “Which commandment is the most important of all?” (29) Jesus answered, “The most important is, ‘Hear, O Israel: The Lord our God, the Lord is one. (30) And 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.’ (31) The second is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.” (32) And the scribe said to him, “You are right, Teacher. You have truly said that he is one, and there is no other besides him. (33) And to love him with all the heart and with all the understanding and with all the strength, and to love one's neighbor as oneself, is much more than all whole burnt offerings and sacrifices.” (34) And when Jesus saw that he answered wisely, he said to him, “You are not far from the kingdom of God.” And after that no one dared to ask him any more questions.
