TSK · Leviticus 15:13

“Thus you are to do for Aaron and for his sons, according to all that I have commanded you; you are to consecrate them for seven days.

And you must not go out from the entrance of the Meeting Tent for seven days, until the day when your days of ordination are completed, because you must be ordained over a seven-day period.

The Seven Days of Purification“The one being cleansed must then wash his clothes, shave off all his hair, and bathe in water, and so be clean. Then afterward he may enter the camp, but he must live outside his tent seven days.

Anyone who touches his bed must wash his clothes, bathe in water, and be unclean until evening.

Purity Regulations from Female Bodily Discharges“‘If she becomes clean from her discharge, then she is to count off for herself seven days, and afterward she will be clean.

Purification from Uncleanness“‘Whoever touches the corpse of any person will be ceremonially unclean seven days.

I will sprinkle you with pure water and you will be clean from all your impurities. I will purify you from all your idols.

Draw near to God and he will draw near to you. Cleanse your hands, you sinners, and make your hearts pure, you double-minded.
