Leviticus 22:5-7

New Revised Standard Version, Anglicised Catholic Edition

⁵ and whoever touches any swarming thing by which he may be made unclean or any human being by whom he may be made unclean—whatever his uncleanness may be— ⁶ the person who touches any such shall be unclean until evening and shall not eat of the sacred donations unless he has washed his body in water. ⁷ When the sun sets he shall be clean; and afterwards he may eat of the sacred donations, for they are his food.
