In the book of Matthew and none of the other Gospels he quotes Jesus as having said they would be cast into the outer darkness.
Matthew 8:12 KJV
But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.
The account of this incident as recorded in Luke chapter 7 does not allude to any comment by Jesus other than:
Luke 7:9 KJV
When Jesus heard these things, he marvelled at him, and turned him about, and said unto the people that followed him, I say unto you, I have not found so great faith, no, not in Israel.
Matthew 22:13 KJV
Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth.
This event is not cited in any other Gospel.
And again in:
Matthew 25:30 KJV
And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.
Again this parable is not cited in any other Gospel.
