Albert Barnes Commentary Leviticus 13:39

"then the priest shall look; and, behold, if the bright spots in the skin of their flesh be of a dull white, it is a tetter, it hath broken out in the skin; he is clean." — Leviticus 13:39 (ASV)

Freckled spot - If (Leviticus 13:12) refers to the Lepra commonis, the Hebrew בהק bôhaq here may denote some kind of eczema, a skin disease of a somewhat similar external character.

(Leviticus 13:38), (Leviticus 13:39) would seem more in their natural place between (Leviticus 13:17–18).
