And he said, “It is what comes out of a person that defiles. For it is from within, from the human heart, that evil intentions come: fornication, theft, murder, adultery, avarice, wickedness, deceit, licentiousness, envy, slander, pride, folly. All these evil things come from within, and they defile a person.”
What then should we say? That the law is sin? By no means! Yet, if it had not been for the law, I would not have known sin. I would not have known what it is to covet if the law had not said, “You shall not covet.”
You shall not covet your neighbor's house; you shall not covet your neighbor's wife, or male or female slave, or ox, or donkey, or anything that belongs to your neighbor.
You want something and do not have it; so you commit murder. And you covet something and cannot obtain it; so you engage in disputes and conflicts. You do not have, because you do not ask.
The commandments, “You shall not commit adultery; You shall not murder; You shall not steal; You shall not covet”; and any other commandment, are summed up in this word, “Love your neighbor as yourself.”
