Numbers 12:15

Then He said, “Return your hand into your bosom.” So he returned his hand into his bosom, and when he took it out of his bosom, behold, it returned to being like the rest of his flesh.

“The one to be cleansed shall then wash his clothes and shave off all his hair and bathe in water and be clean. Now afterward, he may enter the camp, but he shall stay outside his tent for seven days.

“Command the sons of Israel that they send away from the camp every leper and everyone having a discharge and everyone who is unclean because of a dead person.
