Leviticus 13:57 Meaning and Commentary

Leviticus 13:57

And if it appear still in the garment, either in the warp, or
in the woof, or in anything of skin
After the piece has been rent out, in another part of the garment where before it was not seen: it [is] a spreading [plague];
or leprosy; a flourishing one, as the word signifies, a growing and increasing one: thou shalt burn that wherein the plague [is] with fire;
according to Aben Ezra, only that part in which the plague was; but Jarchi says the whole garment; with whom Ben Gersom seems to agree, who reads the words, thou shall burn it, with that in which the plague is; the whole garment, skin, warp, or woof, along with the part in which the leprosy is.

Leviticus 13:57 In-Context

55 After it has been washed, the priest is to reexamine the contamination. If the appearance of the contaminated article has not changed, it is unclean. Even though the contamination has not spread, you must burn up the fabric. It is a fungus on the front or back [of the fabric].

56 "If the priest examines [it], and the contamination has faded after it has been washed, he must cut the contaminated section out of the fabric, the leather, or the warp or woof.

57 But if it reappears in the fabric, the warp or woof, or any leather article, it has broken out again. You must burn up whatever is contaminated.

58 But if the contamination disappears from the fabric, the warp or woof, or any leather article, which have been washed, it is to be washed again, and it will be clean.

59 "This is the law concerning a mildew contamination in wool or linen fabric, warp or woof, or any leather article, in order to pronounce it clean or unclean."
