Matthew 22:37, 39-40

And Jesus replied to him, “ ‘YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND.’ [Deut 6:5]

The second is like it, ‘YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF [that is, unselfishly seek the best or higher good for others].’ [Lev 19:18; Matt 19:19] The whole Law and the [writings of the] Prophets depend on these two commandments.”
