The Law of the Red Heifer and the Water of Purification in Numbers Chapter 19

The corpse like quality of the person who has been struck by leprosy is particularly important to notice. When aaron described miriam after she had been struck with leprosy in numbers chapter 12, he compared her to the corpse of a still born infant. The law concerning the red heifer involves cedar wood and hyssop and scarlet yarn, all joined with the red Heifer in the fire. Whoever touches the dead body of any person shall be unclean seven days. But if he does not cleanse himself on the third ayand on the seventh day, he will not become clean.
