'Seventh Day' in the Bible

"'If anyone dies very suddenly beside him and he defiles his consecrated head, then he must shave his head on the day of his purification -- on the seventh day he must shave it.

On the seventh day Elishama son of Ammihud, leader of the Ephraimites, presented an offering.

He must purify himself with water on the third day and on the seventh day, and so will be clean. But if he does not purify himself on the third day and the seventh day, then he will not be clean.

And the clean person must sprinkle the unclean on the third day and on the seventh day; and on the seventh day he must purify him, and then he must wash his clothes, and bathe in water, and he will be clean in the evening.

On the seventh day you are to have a holy assembly, you must do no regular work.

"'On the seventh day you must offer seven bulls, two rams, and fourteen lambs one year old, all without blemish,

"Any of you who has killed anyone or touched any of the dead, remain outside the camp for seven days; purify yourselves and your captives on the third day, and on the seventh day.

You must wash your clothes on the seventh day, and you will be ceremonially clean, and afterward you may enter the camp.'"
