When he was set down on the judgment seat, his wife sent unto him, saying, Have thou nothing to do with that just man: for I have suffered many things this day in a dream because of him.
Note 3 at Mt 27:19: Matthew was the only writer to record Pilate's wife coming to him with the details of this dream. Secular accounts record her name as Claudia. She was the only one who spoke for, instead of against, Jesus' life during the trial.
This dream, no doubt, came from God since she had to have dreamed it before she knew of Jesus being brought to Pilate. The Lord not only bore witness in Pilate's heart as to the innocence of Jesus, but He also gave Pilate's wife a very clear message through this dream. Pilate was not innocent in this matter.
