Albert Barnes Commentary Leviticus 13:7

"But if the scab spread abroad in the skin, after that he hath showed himself to the priest for his cleansing, he shall show himself to the priest again:" — Leviticus 13:7 (ASV)

Seen by the priest for his cleansing - The meaning of these words is doubtful. They probably mean “seen by the priest and pronounced clean,” and refer to the visit of the suspected leper to the priest at the end of the second week. But some have taken the words to mean “seen by the priest with a view to be pronounced clean,” and regard the sentence of the priest as provisional, holding good only until the symptoms may appear to resume their progress. Compare (Leviticus 13:35).
