34But when the Pharisees had heard that he had put the Sadducees to silence, they were gathered together. 35Then one of them, which was a lawyer, asked him a question, tempting him, and saying, 36Master, which is the great commandment in the law? 37Jesus said unto him, Thou shalt love the LORD thy God with all thy heart, and with all thy soul, and with all thy mind. 38This is the first and great commandment. 39And the second is like unto it, Thou shalt love thy neighbour as thyself. 40On these two commandments hang all the law and the prophets.
~ Matthew 22:34-40
