TSK · Leviticus 8:33

Seven days shall the son that is priest in his stead put them on, when he cometh into the tent of meeting to minister in the holy place.

And he that is to be cleansed shall wash his clothes, and shave off all his hair, and bathe himself in water; and he shall be clean: and after that he shall come into the camp, but shall dwell outside his tent seven days.

Seven days shalt thou prepare every day a goat for a sin-offering: they shall also prepare a young bullock, and a ram out of the flock, without blemish.
