Matthew 27:23-24

23And he said, “Why, what has He done that is evil?” But they continued shouting all the louder, “Let Him be crucified!”

24So when Pilate saw that he was getting nowhere, but rather that a riot was breaking out, he took water and washed his hands [to ceremonially cleanse himself of guilt] in the presence of the crowd, saying, “I am innocent of this [righteous] Man’s blood; see to that yourselves.”
