Leviticus 21:20

או גבן — sourcils in O. F. — is one whose eye-brows have their hair long so that they lie over his eyes (Bekhorot 43b) או דק — one who has in his eye a membrane which is called “toile” (web) in old French The word is similar in meaning to (Isaiah 40:22) “It is He that stretcheth out the heavens like a web (כַּדֹּק) (Bekhorot 48a). או תבלל — (from בלל "to mingle") denotes anything that causes a mingling in the eye, e. g., a white line which extends from the white of the eye and intersects the סירא (the iris), which is the ring that encloses the black of the eye which is called prunelle in old French This white line intersects the circle and runs into the black (so that the white and the black of the eye mingle). The Targum rendering of תבלל is חילוז, connected in meaning with חלזון (a kind of worm); he translates it thus because that line resembles a worm. Thus, too, the Sages of Israel name it (the while line) among the blemishes of first-born animals: חלזון נחש עינב (worm, snake, wart) (cf. Bekhorot 38a,b). גרב וילפת — These are kinds of boil; גרב is identical with חרס (mentioned in Deuteronomy 28:27) — a boil which is dry both inside and on the surface. ילפת is identical with the Egyptian lichen, (חזזית) (Sifra, Emor, Section 3 15). Why is it called ילפת (root לפת “to embrace")? Because it continues to cling to the body until the day of death. It is wet on the surface and dry inside. In another passage, however, Scripture gives the name גרב to a boil which is wet on the surface and dry inside, as it is said (Deuteronomy 28:27) "[The Lord will smite thee…] ובגרב ובחרס”, where גרב necessarily denotes a wet boil since חרס (identical with חרש, potsherd) denotes the dry species. But the explanation is as follows: חרס always denotes the dry skin disease, ילפח always the wet one; as to גרב it depends: When Scripture mentions גרב together with חרס it is calling a ילפת by the term ,גרב and when it mentions it (גרב) together with ילפת (as is the case here) it is calling a חרס by the term גרב. Thus is it explained in Bekhorot 41a. מרוח אשך, according to the Targum, מרס פחדין, which signifies one whose פחדין are מרוססין, i. e., one whose testicles are crushed. פחדין has the same meaning as (Job 40:17) “and the sinews of his stones (פחדיו) are wrapped together”.
