'Seventh Day' in the Bible

If death comes suddenly to a man at his side, so that he becomes unclean, let his hair be cut off on the day when he is made clean, on the seventh day.

On the seventh day Elishama, the son of Ammihud, chief of the children of Ephraim:

On the third day and on the seventh day he is to make himself clean with the water, and so he will be clean: but if he does not do this on the third day and on the seventh day, he will not be clean.

Let the clean person do this to the unclean on the third day and on the seventh day: and on the seventh day he is to make him clean; and after washing his clothing and bathing himself in water, he will be clean in the evening.

Then on the seventh day there will be a holy meeting; you may do no field-work.

And on the seventh day seven oxen, two male sheep, fourteen he-lambs of the first year, without any mark:

You yourselves will have to keep outside the tent-circle for seven days, anyone of you who has put any person to death or come near a dead body; and on the third day and on the seventh day make yourselves and your prisoners clean.

And on the seventh day, after washing your clothing, you will be clean, and then you may come into the tent-circle.
