'Cleansing' in the Bible

But if the scab spread abroad in the skin, after that he hath showed himself to the priest for his cleansing, he shall show himself to the priest again:

But if the scall spread abroad in the skin after his cleansing,

This shall be the law of the leper in the day of his cleansing: he shall be brought unto the priest:

And on the eighth day he shall bring them for his cleansing unto the priest, unto the door of the tent of meeting, before Jehovah:

This is the law of him in whom is the plague of leprosy, who is not able to get that which pertaineth to his cleansing.

And when he that hath an issue is cleansed of his issue, then he shall number to himself seven days for his cleansing, and wash his clothes; and he shall bathe his flesh in running water, and shall be clean.
