Leviticus 22:5-8

⁵or whosoever shall touch any unclean reptile, which will defile him, or who shall touch a man, whereby he shall defile him according to all his uncleanness:

⁶whatsoever soul shall touch them shall be unclean until evening; he shall not eat of the holy things, unless he bathe his body in water,

⁷and the sun go down, and then he shall be clean; and then shall he eat of all the holy things, for they are his bread.

⁸He shall not eat that which dies of itself, or is taken of beasts, so that he should be polluted by them: I am the Lord.
