'Seventh' in the Bible

"'If any man dies very suddenly beside him, and he defiles the head of his separation; 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, prince of the children of Ephraim

the same shall purify himself with water on the third day, and on the seventh day he shall be clean: but if he doesn't 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 him; and he shall wash his clothes, and bathe himself in water, and shall be clean at evening.

On the seventh day you shall have a holy convocation: you shall do no servile work.

"'In the seventh month, on the first day of the month, you shall have a holy convocation; you shall do no servile work: it is a day of blowing of trumpets to you.

"'On the tenth day of this seventh month you shall have a holy convocation; and you shall afflict your souls: you shall do no kind of work;

"'On the fifteenth day of the seventh month you shall have a holy convocation; you shall do no servile work, and you shall keep a feast to Yahweh seven days:

"'On the seventh day seven bulls, two rams, fourteen male lambs a year old without blemish;

"Encamp outside of the camp seven days: whoever has killed any person, and whoever has touched any slain, purify yourselves on the third day and on the seventh day, you and your captives.

You shall wash your clothes on the seventh day, and you shall be clean; and afterward you shall come into the camp."
