'Water' in the Bible

For [when] every commandment had been spoken by Moses to all the people according to the law, [he] took the blood of calves with water and scarlet wool and hyssop [and] sprinkled both the scroll itself and all the people,

let us approach with a true heart in the full assurance of faith, our hearts sprinkled [clean] from an evil conscience and our bodies washed with pure water.
