3. Mose 21:16

Directions for the sons (descendants) of Aaron who were afflicted with bodily imperfections. As the spiritual nature of a man is reflected in his bodily form, only a faultless condition of body could correspond to the holiness of the priest; just as the Greeks and Romans required, for the very same reason, that the priests should be ὁλόκληροι, integri corporis (Plato de legg. 6, 759; Seneca excerpt. controv. 4, 2; Plutarch quaest. rom. 73). Consequently none of the descendants of Aaron, "according to their generations," i.e., in all future generations (see Exo 12:14), who had any blemish (mum, μῶμος, bodily fault) were to approach the vail, i.e., enter the holy place, or draw near to the altar (in the court) to offer the food of Jehovah, viz., the sacrifices. No blind man, or lame man, or charum, κολοβόριν (from κολοβός and ῥίν), naso mutilus (lxx), i.e., one who had sustained any mutilation, especially in the face, on the nose, ears, lips, or eyes, not merely one who had a flat or stunted nose; or שׂרוּע, lit., stretched out, i.e., one who had anything beyond what was normal, an ill-formed bodily member therefore; so that a man who had more than ten fingers and ten toes might be so regarded (Sa2 21:20).

The priesthood being confined to one particular family, and entailed upon all the male issue of that family throughout their generations, it was very likely that some or other in after-ages that were born to the priesthood would have natural blemishes and deformities: the honour of the priesthood would not secure them from any of those calamities which are common to men. Divers blemishes are here specified; some that were ordinarily for life, as blindness; others that might be for a time, as a scurf or scab, and, when they were gone, the disability ceased. Now, I. The law concerning priests that had blemishes was, 1. That they might live upon the altar (Lev 21:22): He shall eat of the sacrifices with the other priests, even the most holy things, such as the show-bread and the sin-offerings, as well as the holy things, such as the tithes and first-fruits, and the priests' share of the peace-offerings. The blemishes were such as they could not help, and therefore, though they might not work, they must not starve. Note, None must be abused for their natural infirmities. Even the deformed child in the family must have its child's part. 2. Yet they must not serve at the altar, at either of the altars, nor be admitted to attend or assist the other priests in offering sacrifice or burning incense, Lev 21:17, Lev 21:21, Lev 21:23. Great men choose to have such servants about them as are sightly, and it was fit that the great God should have such in his house then, when he was pleased to manifest his glory in external indications of it. But it was especially requisite that comely men should be chosen to minister about holy things, for the sake of the people, who were apt to judge according to outward appearance, and to think meanly of the service, how honourable soever it was ma…
