Leviticus 22:6
“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.”
What man soever of the seed of Aaron is a leper, or hath a running issue; he shall not eat of the holy things, until he be clean. And whoso toucheth any thing that is unclean by the dead, or a man whose seed goeth from him;
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;
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.
And when the sun is down, he shall be clean, and shall afterward eat of the holy things; because it is his food.
That which dieth of itself, or is torn with beasts, he shall not eat to defile himself therewith: I am the Lord.
