'Covet' in the Bible

What then shall we say? [Is] the law sin? May it never be! But I would not have known sin except through the law, for I would not have known covetousness if the law had not said, "Do not covet."

For the [commandments], "You shall not commit adultery, you shall not commit murder, you shall not steal, you shall not covet," and if [there is] any other commandment, are summed up in this statement: "You shall love your neighbor as yourself."
