Leviticus

A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.

And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.

For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.

And the second is like unto it, Thou shalt love thy neighbour as thyself.

On these two commandments hang all the law and the prophets.
