'Covet' in the Bible

What shall we say then? Is the law sin? Absolutely not! Certainly, I would not have known sin except through the law. For indeed I would not have known what it means to desire something belonging to someone else if the law had not said, "Do not covet."

For the commandments, "Do not commit adultery, do not murder, do not steal, do not covet," (and if there is any other commandment) are summed up in this, "Love your neighbor as yourself."
