The second case (Leviticus 13:9-17): if the leprosy broke out without previous eruptions.

Leviticus 13:9-11

"If a mole of leprosy is in a man, and the priest to whom he is brought sees that there is a white rising in the skin, and this has turned the hair white, and there is raw (proud) flesh upon the elevation, it is an old leprosy." The apodosis to Leviticus 13:9 and Leviticus 13:10 commences with Leviticus 13:11. חי בּשׂר living, i.e., raw, proud flesh. מחיה the preservation of life (Genesis 45:5), sustenance (Judges 6:4); here, in Leviticus 13:10 and Leviticus 13:24, it signifies life in the sense of that which shows life, not a blow or spot (נגע, from מחה to strike), as it is only in a geographical sense that the verb has this signification, viz., to strike against, or reach as far as (Numbers 34:11). If the priest found that the evil was an old, long-standing leprosy, he was to pronounce the man unclean, and not first of all to shut him up, as there was no longer any doubt about the matter.
