Albert Barnes Commentary Matthew 22:13

"Then the king said to the servants, Bind him hand and foot, and cast him out into the outer darkness; there shall be the weeping and the gnashing of teeth." — Matthew 22:13 (ASV)

Cast him into outer darkness. See Barnes on Matthew 8:12.

This, without doubt, refers to the future punishment of the hypocrite (Matthew 23:23–33; Matthew 24:51).
