Ezekiel 44:24-26

Complete Jewish Bible

²⁴ They are to be judges in controversies, and they are to render decisions in keeping with my rulings. At all my designated festivals they are to keep my laws and regulations, and they are to keep my shabbats holy. ²⁵ They are not to come to any dead person, because this would make them unclean; however, for father, mother, son, daughter, brother or sister who has had no husband they may make themselves unclean. ²⁶ After a cohen has been purified, he is to wait seven days.
