'Covet' in the Bible

What should we say, then? Is the Law sinful? Of course not! In fact, I wouldn't have become aware of sin if it had not been for the Law. I wouldn't have known what it means to covet if the Law had not said, "You must not covet."

For the commandments, "You must not commit adultery; you must not murder; you must not steal; you must not covet," and every other commandment are summed up in this statement: "You must love your neighbor as yourself."
