'Fretting' in the Bible

And he shall look on the plague on the seventh day: if the plague be spread in the garment, either in the warp, or in the woof, or in a skin, or in any work that is made of skin; the plague is a fretting leprosy; it is unclean.

He shall therefore burn that garment, whether warp or woof, in woollen or in linen, or any thing of skin, wherein the plague is: for it is a fretting leprosy; it shall be burnt in the fire.

And the priest hath seen that which hath the plague after it hath been washed, and lo, the plague hath not changed its aspect, and the plague hath not spread, -- it is unclean; with fire thou dost burn it; it is a fretting in its back-part or in its front-part.

and if it still be seen in the garment, or in the warp, or in the woof, or in any vessel of skin, it is a fretting; with fire thou dost burn it -- that in which the plague is.

Then the priest shall come and look, and, behold, if the plague be spread in the house, it is a fretting leprosy in the house: it is unclean.
