'Seventh Day' in the Bible

" 'If someone dies suddenly and makes the head of his separation unclean, he will shave off [the hair of] his head on the day of his cleansing; on the seventh day he will shave it off.

On the seventh day Elishama son of Ammihud, leader of the descendants of Ephraim:

He will purify himself on the third day, and on the seventh day he will be clean. If he does not purify himself on the third day, he will not be clean on the seventh day.

The clean [person] will spatter the unclean on the third day and on the seventh day; and on the seventh day he will purify him, and he will wash his garments; he will bathe in the waters, and in the evening he will be clean.

On the seventh day you will have a holy convocation; {you will not do any regular work}.

" 'On the seventh day: seven bulls, two rams, fourteen male lambs without defect {in their first year};

And you, camp outside the camp seven days; all who killed a person and all who touched the slain purify yourselves on the third day and on the seventh day, you and your captives.

And you will wash your garments on the seventh day and be clean, and afterward you will come into the camp."
