Levítico 14:8

Y el que se purifica lavará sus vestidos, y raerá todos sus pelos, y se ha de lavar con agua, y será limpio: y después entrará en el real, y morará fuera de su tienda siete días.

And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days.
