Matthew 22:35-40 (NKJV)
³⁵  Then one of them, a lawyer, asked Him a question, testing Him, and saying,
³⁶  “Teacher, which is the great commandment in the law?”
³⁷  Jesus said to him, “‘You shall love the LORD your God with all your heart, with all your soul, and with all your mind.’
³⁸  This is the first and great commandment.
³⁹  And the second is like it: ‘You shall love your neighbor as yourself.’
⁴⁰  On these two commandments hang all the Law and the Prophets.”
