A complement to post #13
In every generation, there are many prophecies or foretelling that such and such things will happen, and then the public will keep anticipating the fulfilment and the occurrence of such prophecies or foretellings:
One of such foretelling known by the public at the time of the Christ was that: a certain man will rise from the dead.
So some people (or some disciples) applied this prophecy or foretelling to the case of the Christ.
Therefore, when they saw him alive three days after the incident of the crucifixion, they said: "It must be Jesus is the one meant by the prophecy that he will rise from the dead."
While in fact, Jesus Christ did not tell people that he will die then will be resurrected once again.
Another example of exploiting some foretellings or prophecies circling among the public:
Muslims, particularly the Shiaa, had a foretelling that the Mahdi will be absent for some period of time then he will return again and will rise (or be resurrected), and in fact he is called the (Rising One) or the (Resurrected One)
So a cunning man exploited such prophecy or foretelling and said: The son of Hassan Askary (the 11th imam of the Shiaa) had a son, and the son has been absent and will return once again.
People at that time did not accept such claim, but by time, it became dogmatic; so this is another example of exploiting the public prophecies or foretellings.
