Matt 22:35-40

35and one of them, a lawyer, asked him a question to test him.36“Teacher, 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.”
