Charles Ellicott Commentary Matthew 22:12

"and he saith unto him, Friend, how camest thou in hither not having a wedding-garment? And he was speechless." — Matthew 22:12 (ASV)

Friend —(See Note on Matthew 20:13.) The question implies that the act was strange, unexpected, and inexcusable.

He was speechless —The verb is the same as the one translated put to silence in Matthew 22:34, and it literally describes the silence of someone who has been gagged.
