Mark 12:28-34
One of the scribes came up and heard them arguing, and recognizing that He had answered them well, asked Him,“ What commandment is the foremost of all?”Jesus answered,“ The foremost is,‘ Hear, Israel! The Lord is our God, the Lord is one;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.’The second is this:‘ You shall love your neighbor as yourself.’ There is no other commandment greater than these.”And the scribe said to Him,“ Well said, Teacher; You have truly stated that He is One, and there is no other besides Him;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 the burnt offerings and sacrifices.”When Jesus saw that he had answered intelligently, He said to him,“ You are not far from the kingdom of God.” And then, no one dared any longer to question Him.
Matthew 22:34-40
But when the Pharisees heard that Jesus had silenced the Sadducees, they gathered together.And one of them, a lawyer, asked Him a question, testing Him:“ Teacher, which is the great commandment in the Law?”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.’This is the great and foremost commandment.The second is like it,‘ You shall love your neighbor as yourself.’Upon these two commandments hang the whole Law and the Prophets.”
