A.T. Robertson 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)

Was speechless (εψιμωθη). Was muzzled, dumb from confusion and embarrassment. It is used of the ox (1 Timothy 5:18).

The outer darkness (το σκοτος το εξωτερον). See Mt 8:12. All the blacker from the standpoint of the brilliantly lighted banquet hall.

There shall be (εκε εστα). Out there in the outer darkness.
