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 (Leviticus 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, Leviticus 21:17. 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 made by the divine institution, of those that performed it looked despicably or went about it awkwardly. This provision God made for the preserving of the reputation of his altar, that it might not at any time fall under contempt. It was for the credit of the sanctuary that none should appear there who were any way disfigured, either by nature or accident.
II. Under the gospel, 1. Those that labour under any such blemishes as these have reason to thank God that they are not thereby excluded from offering spiritual sacrifices to God; nor, if otherwise qualified for it, from the office of the ministry. There is many a healthful beautiful soul lodged in a crazy deformed body. Yet, 2. We ought to infer hence how incapable those are to serve God acceptably whose minds are blemished and deformed by any reigning vice. Those are unworthy to be called Christians, and unfit to be employed as ministers, that are spiritually blind, and lame, and crooked, whose sins render them scandalous and deformed, so as that the offerings of the Lord are abhorred for their sakes. The deformities of Hophni and Phinehas were worse than any of the blemishes here mentioned. Let such therefore as are openly vicious be put out of the priesthood as polluted persons; and let all that are made to our God spiritual priests be before him holy and without blemish, and comfort themselves with this, that, though in this imperfect state they have spots that are the spots of God's children, yet they shall shortly appear before the throne of God without spot, or wrinkle, or any such thing.
