Leviticus 22:5-7

⁵and that toucheth a creeping beast, and whatever unclean thing, whose touching is foul,

⁶he shall be unclean till to eventide, and he shall not eat these things that be hallowed to me; but when he hath washed his flesh in water,

⁷and the sun hath gone down, then he shall be cleansed, and shall eat hallowed things, for it is his meat.
