'Seventh Day' in the Bible

And if any man dies very suddenly beside him, and he has defiled the head of his consecration, then he shall shave his head in the day of his cleansing, on the seventh day he shall shave it.

On the seventh day Elishama the son of Ammihud, ruler of the sons of Ephraim, offered:

He shall purify himself with it on the third day, and on the seventh day he shall be clean. But if he does not purify himself the third day, then the seventh day he shall not be clean.

And the clean person shall sprinkle on the unclean on the third day, and on the seventh day. And on the seventh day he shall purify himself, and wash his clothes, and bathe himself in water. And he shall be clean at evening.

And on the seventh day you shall have a holy convocation. You shall do no laboring work.

And on the seventh day seven bulls, two rams, and fourteen lambs of the first year without blemish;

And stay outside the camp seven days. Whosoever has killed any person, and whoever has touched any dead one, purify yourselves and your captives on the third day and on the seventh day.

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