Levítico 19

Levítico 19:18

Long before Christ it had been said, "You shall not covet"; long before it had been said, "You shall love your neighbor as yourself," a phrase which, as the apostle says, expresses the fulfillment of the whole law. And as no one loves himself unless he loves God, the Lord says that the whole Law and the Prophets depend on these two commandments. — LETTER 177
