3Say to them, Any man of all the sons of your generations who shall touch the hallowed things which the children of Israel consecrate before the Lord, having his uncleanness upon him, that man shall perish before Me: I am the Lord.
4Any man of Aharon’s offspring who hath leprosy or an unclean effusion shall not eat of the consecrated things until he be clean; and whosoever toucheth any unclean animal, or a man whose seed goeth from him,
5Or a man who toucheth any reptile that maketh him unclean, or a man who maketh him unclean by any of his uncleanness,
6The man who toucheth him shall be unclean until the evening, and may not eat of things consecrated unless he wash his flesh with water.
7But when the sun hath gone down, and he shall have purified himself, he may afterward eat of the hallowed things, for it is his food.
