'Wash' in the Bible

‘The priest shall then write these curses on a scroll and shall wash them off into the water of bitterness;

This is what you shall do to them to [ceremonially] cleanse them: sprinkle the water of purification on them, and let them use a razor over their whole body and wash their clothes, and they will be clean.

Then the priest shall wash his clothes and bathe his body in water; and afterward come into the camp, but he shall be [ceremonially] unclean until evening.

The one who burns the heifer shall wash his clothes and bathe his body in water, and shall be unclean until evening.

The one who gathers the ashes of the heifer shall wash his clothes, and be unclean until evening. This shall be a perpetual statute to the Israelites and to the stranger who lives as a resident alien among them.

Then the clean person shall sprinkle [the water for purification] on the unclean person on the third day and on the seventh day, and on the seventh day the unclean man shall purify himself, and wash his clothes and bathe himself in water, and shall be [ceremonially] clean at evening.

So it shall be a perpetual statute to them. He who sprinkles the water for impurity [on another] shall wash his clothes, and he who touches the water for impurity shall be unclean until evening.

And you shall wash your clothes on the seventh day and be clean, and afterward you may come into the camp.”
