wash one's hands of (something), to

To dismiss or renounce interest in; to turn away and refuse responsibility. The term comes from the Bible, where at Jesus’s trial the Roman governor, Pontius Pilate, saw that he could not save Jesus and “washed his hands before the multitude, saying I am innocent of the blood of this just person” (Matthew 27:24). Shakespeare referred to it directly in Richard II (4.1): “Some of you with Pilate wash your hands.” Dickens and others used it somewhat more lightly: “He had entirely washed his hands of the difficulty” (Bleak House, 1853).
