'Corroding' in the Bible

And he shall see the sore on the seventh day: if the sore have spread in the garment, either in the warp or in the woof, or in a skin, in any work that may be made of skin, the sore is a corroding leprosy: it is unclean.

And they shall burn the garment, or the warp or the woof, of wool or of linen, or anything of skin, wherein the sore is; for it is a corroding leprosy: it shall be burned with fire.

The priest shall examine the article with the mark after it has been washed, and if the mark has not changed color, even though the mark has not spread, it is unclean; you shall burn it in the fire; it is a corroding mildew, whether on the top or on the front of it.

then the priest shall come, and when he looketh, and behold, the plague hath spread in the house, it is a corroding leprosy in the house: it is unclean.
