KJV
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.
BSB
He is to burn the fabric, weave, or knit, whether the contaminated item is wool or linen or leather. Since the mildew is harmful, the article must be burned up.
