Leviticus 13:45

These are the signs of mourning for the dead (cp. Leviticus 10:6; Leviticus 21:10; Ezekiel 24:17; Micah 3:7), leprosy being regarded as a living death and the severest token of the divine displeasure: cp. Numbers 12:12.

47-59. The leprosy of garments. What is described here is not the leprosy that attacks the human being, but a mildew or fungus causing discoloration and corrosion and bearing a superficial resemblance to leprosy: cp. the leprosy of houses, Leviticus 14:33. The regulations regarding this so-called 'leprosy' were no doubt valuable for sanitary reasons; but they would also serve to 'teach the Hebrew to hate even the appearance of evil.' Cp. what St. Jude says (Leviticus 13:23) of the Christian 'hating even the garment spotted by the flesh.'
