I never thought of Caiaphas as a prophet.

I never noticed this before.  I never thought if Caiaphas as a prophet but here it says he prophesied.

John 11:49-52(NKJV)

And one of them, Caiaphas, being high priest that year, said to them, “You know nothing at all, 

nor do you consider that it is expedient for us that one man should die for the people, and not that the whole nation should perish.” 

Now this he did not say on his own authority; but being high priest that year he prophesied that Jesus would die for the nation, 

and not for that nation only, but also that He would gather together in one the children of God who were scattered abroad.
