Exclusive information from Matthew.  Number 6:  The dream of Pilot's wife.  Matthew 27:19
  
Jesus was a threat to the old order--the priests and scribes.  The Pharisees and Sadducees.  He made them look bad and they hated him.  Matthew 21: 12-13 "And Jesus went into the temple of God, and cast out all those who sold (sheep and doves, etc. for sacrifices)...and overthrew the tables of the money changers..."  Then he said, "It is written, My house shall be called the house of prayer; but you have made it a den of thieves."

I imagine there was a kickback from all the sales going on in the temple.  But Jesus began to heal the blind and the lame which came to him in the temple.  Vs. 15 "And when the chief priests and scribes saw the wonderful things that he did, and the children crying the temple, and saying Hosanna to the Son of David; they were sore displeased."  I'd say they were jealous and bitter and mean.

Things went downhill after that.  Eventually the priests and elders convinced Pilot to condemn Jesus to death.  Matt. 27:1 "When the morning was come, all the chief priests and elders of the people took counsel against Jesus to put him to death..."

Pilot gave the people a choice of whom he would release: Jesus or Barabbus--who was a horrible criminal.  Pilot knew that they (the priests) had delivered Jesus to him because of envy. (vs. 18)  At this point, Pilot's wife approaches him:  (vs. 19) "When he was set down on the judgment seat, his wife sent unto him saying, Have...nothing to do with that just man:  for I have suffered many things this day in a dream because of him."  Pilot's wife knew Jesus was an innocent man.  I am sure she was disgusted that Pilot--who had the power to release Jesus--was too weak and afraid of the people and the priests to do so.  He didn't want an uprising.  I would have been disgusted.  Here's a man with all the power to do the right thing.  And he doesn't.  He should have listened to his wife.

Interesting how God uses people.   I think that God gave her the dream.
