Deuteronomy 21:6

And He said, “What have you done? The voice of your brother’s blood is crying out to Me from the ground.

“So innocent blood will not be shed in the midst of your land which Yahweh your God gives you as an inheritance, and bloodguiltiness be on you.

“May it whirl on the head of Joab and on all his father’s house; and may one who has a discharge, or who is a leper, or who takes hold of a spindle, or who falls by the sword, or who lacks bread not be cut off from the house of Joab.”

Now when Pilate saw that he was accomplishing nothing, but rather that a riot was starting, he took water and washed his hands in front of the crowd, saying, “I am innocent of this man’s blood; see to that yourselves.”
