Leviticus 10:6-7

Moses then said to Aaron and his remaining sons, Eleazar and Ithamar, “No mourning rituals for you—unkempt hair, torn clothes—or you’ll also die and GOD will be angry with the whole congregation. Your relatives—all the People of Israel, in fact—will do the mourning over those GOD has destroyed by fire. And don’t leave the entrance to the Tent of Meeting lest you die, because GOD’s anointing oil is on you.” They did just as Moses said. * * *
