Negaim 11:3 - 11:4

הצבועים – even at the hands of Heaven.

הבתים בין צבועים – even at the hands of man.

העורות כבתים – and even if they are colored at the hands of man become susceptible to uncleanness through plagues. But the Halakha that colored clothing is not susceptible to uncleanness and even at the hands of Heaven, as it is written (Leviticus 13:47): [“When an eruptive affection occurs in] a cloth of wool or linen fabric,” / "בגד צמר או בבגד פשתים", just as linen/flax is like its creation, even wool is like its creation. And it is written (Leviticus 13:48): “[In the warp or in the woof] of the linen or the wool, [or in a skin or anything made of skin],” just as flax/linen is white, even wool is white, and the colored skins made by man do not become susceptible to uncleanness through plagues, but at the hands of Heave, they do become susceptible to uncleanness through plagues, according to the words of Rabbi Shimon.

ששתיו צבוע – its warp is colored, but that which is colored is not susceptible to uncleanness.

וערבו לבן – but if we follow after the woof which is white, it is susceptible to uncleanness.

הכל הולך אחר הנראה – with undefined clothing the woof is seen, [whereas] with mattresses and bolsters, the warp is seen. But everything is according to the artisanry.

ירקרק – the palest of the pale (green) colors (see Leviticus 13:49 and 14:37).

אדמדם – the red that is among the reddish, meaning to say, that the appearance of the greens and the redness/reddish color in them is very strong. ירקרק/palest of pale green is like the wing of a peacock and like the long and thin foliage of a palm branch (that is prickly). אדמדם/red that is among the reddish is like the nice crimson of the blood.

היה ירקרק כגיסת ולסוף שבוע פשה אדמדם אצל ירקרק:

נשתנה ופשה – as for example, that it was at the outset palest of pale green like a split [Cilician] bean, and at the end of the week, it spread and became large like a rock, but whether it was the starting point of leprosy or whether its spread was red that is among the reddish.

נשתנה ולא פשה – at the beginning it was like a split [Cilician] bean of pale green color and at the end like a split [Cilician] bean of reddish color.

כאילו לא נשתנה – and that which spread requires burning, and that which did not spread, we shut up/isolate/quarantine for a second week.

יראה (בתחלה) – that it is considered as if it hanged to another plague. But the Halakha is not according to Rabbi Yehuda.
