TSK · Leviticus 8:33

Seven days shall the son who is priest in his place put them on, when he comes into the Tent of Meeting to minister in the holy place.

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

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