Leviticus 13:11

Old leprosy. There would doubtless be cases where a man had failed to present himself to the priest at the first occurrence of any questionable sign of possible leprosy, and where the family had neglected to bring him to the priest, knowing what an unfavorable report would mean. When conditions could be hidden no longer, he went or was brought to the priest. If there was a swelling in the flesh, if the hair in the spot had turned white, and there was “quick raw flesh in the rising” it was “an old leprosy,” and the priest should immediately declare him unclean. There was no need to quarantine him for further observation; he need not be shut up for later examination.
