Paladin spell, lvl 1.

It says "A creature cannot benefit more than once from the same casting of this spell."

Do you read this as cant gain the bonus more than once in the same game round (by moving back and forth on it) or once total over the course of the entire spell?

Thanks

Over the course of the entire spell. If they meant each round, it would have said so.
