'Wash' in the Bible

I shall wash my hands in innocence,And I will go about Your altar, O Lord,

Wash me thoroughly from my iniquityAnd cleanse me from my sin.

Purify me with hyssop, and I shall be clean;Wash me, and I shall be whiter than snow.

The righteous will rejoice when he sees the vengeance;He will wash his feet in the blood of the wicked.
