Leviticus 22:4-6

Modern English Version

⁴ If a man of the offspring of Aaron is a leper or has a discharge, he shall not eat of the holy offerings until he is clean. And whoever touches anything that is unclean by contact with the dead or a man who had an emission of semen, ⁵ or whoever touches any crawling thing whereby he may be made unclean, or a man from whom he may receive uncleanness, whatever uncleanness he has, ⁶ the person who has touched any such thing shall be unclean until evening, and shall not eat of the holy things unless he washes his body with water.
