But if it reappears in the fabric, weave, or knit, or on any leather article, it is spreading. You must burn the contaminated article.
KJV
And if it appear still in the garment, either in the warp, or in the woof, or in any thing of skin; it [is] a spreading [plague]: thou shalt burn that wherein the plague [is] with fire.
ASV
and if it appear still in the garment, either in the warp, or in the woof, or in anything of skin, it is breaking out: thou shalt burn that wherein the plague is with fire.
