Leviticus 22:4-7

⁴And the man of the seed of Aaron the priest, if he should have leprosy or issue of the reins, shall not eat of the holy things, until he be cleansed; and he that touches any uncleanness of a dead body, or the man whose seed of copulation shall have gone out from him,

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.
