John Trapp on Matthew 18:32

Verse 32. O thou wicked servant] Wicked with a witnesse, as that wicked Haman, so Esther called him (Est. 7. 6.) who never till then had heard his true title. God will have a time to tell every man his own: and for those that are now so haughty and passionate, that none dare declare their way to their face, God will lay them low enough in the slimy valley, where are many already like them, and more shall come after them, Iob 21, 31, 32.
