Leviticus 22:5-7

⁵or whosoever toucheth any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatsoever uncleanness he hath;

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

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