Matthew 27:19, 24

Besides, while he was sitting on the judgment seat, his wife sent word to him, “Have nothing to do with that righteous man, for I have suffered much because of him today in a dream.”

So when Pilate saw that he was gaining nothing, but rather that a riot was beginning, he took water and washed his hands before the crowd, saying, “I am innocent of this man’s blood; see to it yourselves.”
