Leviticus 22:5-8

⁵Or whoever toucheth any creeping animal, by which he may be made unclean, or a man of whom he may take uncleanness, whatever uncleanness he hath:

⁶The soul which hath touched any such shall be unclean until evening, and shall not eat of the holy things, unless he shall wash his flesh with water.

⁷And when the sun is set, he shall be clean, and shall afterward eat of the holy things, because it is his food.

⁸That which dieth of itself, or is torn by beasts , he shall not eat to defile himself with it: I am the LORD.
