Leviticus

²Speak unto Aaron and to his sons, that they separate themselves from the holy things of the children of Israel, which they hallow unto me, and that they profane not my holy name: I am the LORD. ³Say unto them, Whosoever he be of all your seed throughout your generations, that approacheth unto the holy things, which the children of Israel hallow unto the LORD, having his uncleanness upon him, that soul shall be cut off from before me: I am the LORD. ⁴What man soever of the seed of Aaron is a leper, or hath an 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; 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 toucheth any such shall be unclean until the even, and shall not eat of the holy things, unless he bathe his flesh in water. ⁷And when the sun is down, he shall be clean; and afterward he shall eat of the holy things, because it is his bread. ⁸That which dieth of itself, or is torn of beasts, he shall not eat to defile himself therewith: I am the LORD.
