Leviticus 13:47-51 Amplified Bible (AMP)

47. The garment also that the disease of leprosy [symbolic of sin] is in, whether a wool or a linen garment, [Jude 23; Rev. 3:4.]

48. Whether it be in woven or knitted stuff or in the warp or woof of linen or of wool, or in a skin or anything made of skin,

49. If the disease is greenish or reddish in the garment, or in a skin or in the warp or woof or in anything made of skin, it is the plague of leprosy; show it to the priest.

50. The priest shall examine the diseased article and shut it up for seven days.

51. He shall examine the disease on the seventh day; if [it] is spread in the garment, or in the article, whatever service it may be used for, the disease is a rotting or corroding leprosy; it is unclean.
