Leviticus 22:7

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

⁶  The 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.

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

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

⁹  They shall therefore keep mine ordinance, lest they bear sin for it, and die therefore, if they profane it: I the LORD do sanctify them.
