21:1-24 Laws concerning the priests. - As these priests were types of Christ, so all ministers must be followers of him, that their example may teach others to imitate the Saviour. Without blemish, and separate from sinners, He executed his priestly office on earth. What manner of persons then should his ministers be! But all are, if Christians, spiritual priests; the minister especially is called to set a good example, that the people may follow it. Our bodily infirmities, blessed be God, cannot now shut us out from his service, from these privileges, or from his heavenly glory. Many a healthful, beautiful soul is lodged in a feeble, deformed body. And those who may not be suited for the work of the ministry, may serve God with comfort in other duties in his church.

16-24. Whosoever he be … hath any blemish, let him not approach to offer the bread of his God—As visible things exert a strong influence on the minds of men, any physical infirmity or malformation of body in the ministers of religion, which disturbs the associations or excites ridicule, tends to detract from the weight and authority of the sacred office. Priests laboring under any personal defect were not allowed to officiate in the public service; they might be employed in some inferior duties about the sanctuary but could not perform any sacred office. In all these regulations for preserving the unsullied purity of the sacred character and office, there was a typical reference to the priesthood of Christ (Heb 7:26).
