What is in a name? Perhaps a reputation?
Names are not just what are given to us by our parents to distinguish us from one kid or another. Our names have a way of being tarnished or gleaming with our own reputation.
So, it can also be with God.
You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes His name in vain.
You shall not take the name of the Lord, your God, in vain. For the Lord will not leave unpunished him who takes his name in vain.
