And he shall look on the plague on the seventh day: if the plague be spread in the garment, either in the warp, or in the woof, or in a skin, or in any work that is made of skin; the plague is a fretting leprosy; it is unclean.

and he shall look on the plague on the seventh day: if the plague be spread in the garment, either in the warp, or in the woof, or in the skin, whatever service skin is used for; the plague is a fretting leprosy; it is unclean.

51And on the seventh day when he looketh on it again, if he find that it if grown, it is a Axed leprosy: he shall judge the garment unclean, and every thing wherein it shall be found:

And he shall see the sore on the seventh day: if the sore have spread in the garment, either in the warp or in the woof, or in a skin, in any work that may be made of skin, the sore is a corroding leprosy: it is unclean.

and he hath seen the plague on the seventh day, and the plague hath spread in the garment, or in the warp, or in the woof, or in the skin, of all that is made of skin for work; the plague is a fretting leprosy, it is unclean.

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 he shall look on the plague on the seventh day: if the plague be spread in the garment, or in the warp, or in the woof, or in the skin, whatever service skin is used for, the plague is a malignant leprosy: it is unclean.

And on the seventh day, having looked at it again, if he detects an increase, it is a persistent leprosy; he shall judge the garment to be polluted, along with everything with which it has been found.

Postea inspiciet plagam illam die septimo: si creverlt plaga illa per vestera, vel per subtegmen, vel pellem in omni opere pelliceo, lepra corodentis plagae est, immunda est.

A fretting leprosy - i. e. a malignant or corroding leprosy. What was the nature of the leprosy in clothing, which produced greenish or reddish spots, cannot be precisely determined. It was most likely destructive mildew, perhaps of more than one kind.

And he shall look on the plague on the seventh day,.... To see whether there is any alteration in it in that space of time:
if the plague be spread in the garment, either in the warp or in the woof, or in a skin, or in any work that is made of skin; the green and red spot be spread more and more in either of them, whether the colour remains the same or not, be changed, the green into red, or the red into green, yet if there was a spreading, it was a sign of leprosy. According to the Jewish canon (s), if the plague was green and spread red, or red and spread green, it was unclean; that is, as Bartenora (t) explains it, if it was red in the size of a bean, and at the end of the week the red had spread itself to green; or if at the beginning it was green like a bean, and at the end of the week had spread itself to the size of a shekel, and the root or spread of it was become red:
the plague is a fretting leprosy; according to Jarchi, a sharp and pricking one, like a thorn; which signification the word has in Ezekiel 28:24. Ben Gersom explains it, which brings a curse, corruption, and oldness into the thing in which it is; an old "irritated, exasperated" leprosy, as Bochart (u), from the use of the word in the Arabic tongue, translates it:
it is unclean; and the garment or thing in which it is.
