'Biting' in the Bible

And he is to see the mark on the seventh day; if the mark is increased in the clothing, or in the threads of the material, or in the leather, whatever the leather is used for, it is the disease biting into it: it is unclean.

And the clothing, or the wool or linen material, or anything of leather in which is the disease, is to be burned: for the disease is biting into it; let it be burned in the fire.
