Chabad.org — Chumash, English translation + Rashi for Vayikra 13:2
Torah Temimah cites Yerushalmi Niddah 2:7 for the procedural requirement to bring skin afflictions to priestly examination.
Sefaria — Yerushalmi Niddah 2:7
English: Scripture says: “He shall be brought to Aaron the priest or to one of his sons, the priests.”
Textual requirement
The passive wording “he shall be brought” requires priestly examination; the affected person cannot establish the status of a skin affliction by self-presentation alone.
