Who pronounce Jesus sentence?

In Matthew chapter 27 (King James Version) begins the trial of Jesus. Although Pilate tried to absolve himself of responsibility (Pilate's wife tried to warn him) he agreed to the death of Jesus as a way to satisfy the Jews. Pilate was the Roman govenor

of that area of Israel and didn't want any trouble from the people.

It is interesting to note that although Pilate sentenced Christ Jesus to death, to show he didn't want any responsibility for the action he washed his hands in clean water from a bowl. That is where we get our expression "to wash our hands of (something)" when

we don't want to absolve ourselves of responsibility.
