Matthew 22:35-40
New International Version
One of them, an expert in the law, tested him with this question: “Teacher, which is the greatest commandment in the Law?”
Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’[a] 38 This is the first and greatest commandment. And the second is like it: ‘Love your neighbour as yourself.’ All the Law and the Prophets hang on these two commandments.”
