'Washed' in the Bible

Let all my wrongdoing be washed away, and make me clean from evil.

Make me free from sin with hyssop: let me be washed whiter than snow.

The upright man will be glad when he sees their punishment; his feet will be washed in the blood of the evil-doer.

Verily I have cleansed my heart in vain, and washed my hands in innocency.
