'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.

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.
