'Purification' in the Bible

‘When the man with the discharge becomes cleansed from his discharge, he shall count off seven days for his purification; he shall then wash his clothes and bathe his body in running water and will become clean.

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 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.

‘But the man who is unclean and does not purify himself, that person shall be cut off from among the assembly, because he has defiled the sanctuary of the Lord. The water for purification has not been sprinkled on him; he is unclean.

then you shall bring her [home] to your house, and she shall shave her head and trim her nails [in preparation for mourning].

everyone who sets his heart to seek God—the Lord God of his fathers—even though it is not in accordance with the [ceremonial] purification [rules] of the sanctuary.”

And they performed the worship of their God and the service of purification; so did the singers and gatekeepers, as David and his son Solomon had commanded.

Let the king appoint administrators in all the provinces of his kingdom, and have them gather all the beautiful young virgins to the citadel in Susa, into the harem, under the custody of Hegai, the king’s eunuch, who is in charge of the women; and let their beauty preparations be given to them.

Now the young woman pleased Hegai and found favor with him. So he quickly provided her with beauty preparations and her [portion of] food, and he gave her seven choice maids from the king’s palace; then he transferred her and her maids to the best place in the harem.

So when the Lord has completed all His work [of judgment] on Mount Zion and on Jerusalem, He will say, “I will punish the fruit [the thoughts, the declarations, and the actions] of the arrogant heart of the king of Assyria and the haughtiness of his pride.”
