When Pilate saw that he could not prevail, but rather that unrest was beginning, he took water and washed his hands before the crowd, saying, “I am innocent of the blood of this righteous Man. See to it yourselves.”
let us draw near with a true heart in full assurance of faith, having our hearts sprinkled to cleanse them from an evil conscience, and our bodies washed with pure water.
Figuratively this is like baptism, which also saves us now. It is not washing off the dirt from the body, but a response to God from a good conscience through the resurrection of Jesus Christ,
