Charles Ellicott Commentary Leviticus 21:20

"or crook-backed, or a dwarf, or that hath a blemish in his eye, or is scurvy, or scabbed, or hath his stones broken;" — Leviticus 21:20 (ASV)

Or crookbacked. —Rather, or whose eyebrows cover his eyes. This is the sense given to this clause during the Second Temple period. Hence, the ancient Chaldee version of Jonathan translates it, “whose eyebrows lying cover his eyes.” That is, the hair of the eyebrows is so thick, heavy, and long that it joins together and covers his eyes, thus interfering with his eyesight and rendering him unsightly in appearance.

Or a dwarf, or who has a blemish in his eye. —Better, or has a cataract or a fusion of the white and black in his eye, as the administrators of the Law during the Second Temple period interpret the two defects spoken of here.

Or be scurvy, or scabbed. —According to the authorities in the time of Christ, both of these are kinds of ulcers or scurvy; the former is a scab that is dry both within and without, while the second is a scab that is moist within and dry without, and which clings to a man until he dies.

Or has his stones broken. —That is, one whose testicles are injured. This included several kinds of defects, which are shown in the different renderings of the ancient versions, but all refer to the same location of the blemish.
