Matthew 22:34-40
34But the Pharisees, when they heard that he had put the Sadducees to silence, gathered themselves together. 35And one of them, a lawyer, asked him a question, trying him, and saying, 36Teacher, which is the great commandment in the law? 37And Jesus 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 a second is like unto it, Thou shalt love thy neighbor as thyself. 40On these two commandments hang the whole law and the prophets.
