Commentators unanimously agree that "You shall not steal" extends far beyond simple theft. It condemns any action that unjustly enriches oneself at another's expense. This includes business fraud, taking advantage of someone's ignorance or need, withholding fair wages, accumulating debt without the intent to repay, and even plunder on a national scale. As John Calvin notes, God uses the blunt word "theft" to cut through any excuses or euphemisms we might use for our unjust gains.
