"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.

He shall put on the holy linen coat, and he shall have the linen breeches on his body, and shall put on the linen sash, and he shall be clothed with the linen turban. They are the holy garments. He shall bathe his body in water, and put them on.

Then he shall bathe himself in water in a holy place, and put on his garments, and come out and offer his burnt offering and the burnt offering of the people, and make atonement for himself and for the people.

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.
