Leviticus 13:54

And if the priest look, and, behold, the plague be somewhat dark after the washing of it,.... Is become of a weaker colour, either not quite so green, or not quite so red as it was, or is "contracted", and does not spread itself; see Gill on Lev 13:6; but is rather become less:

then he shall rend it out of the garment, or out of the skin, or out of the warp, or out of the woof; that is, that piece which has the plague in it, and burn it, as Jarchi says; that so the whole may not be lost, which is otherwise pure, and clean, and free from any infection. The manner of expression confirms what I have observed on Lev 13:48; that the warp and woof are considered as separate things, and as before they are wove together, or wrought into one garment. This rending out may denote the denying of ungodliness and worldly lusts, the parting with right eye and right hand sins, and having no fellowship with the unfruitful works of darkness.
