Matthew 22:34-40: 34When the Pharisees heard that he had silenced the Sadducees, they gathered together, 35and one of them, a lawyer, asked him a question to test him. 36Teacher, which commandment in the law is the greatest? 37He said to him, " 'You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.' 38This is the greatest and first commandment. 39And a second is like it: 'You shall love your neighbor as yourself.' 40On these two commandments hang all the law and the prophets."
