Adam Clarke
He that let go the goat - shall wash, etc. - Not only the person who led him away, but the priest who consecrated him, was reputed unclean, because the goat himself was unclean, being considered as bearing the sins of the whole congregation. On this account both the priest and the person who led him to the wilderness were obliged to wash their clothes and bathe themselves, before they could come into the camp.
