10 For what was glorious has no glory now in comparison with the surpassing glory.

Read 2 Corinthians 3:10 Using Other Translations

For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
Indeed, in this case, what once had glory has come to have no glory at all, because of the glory that surpasses it.
In fact, that first glory was not glorious at all compared with the overwhelming glory of the new way.
