Leviticus 21

7-9. They shall not take a wife that is a whore, or profane--Private individuals might form several connections, which were forbidden as inexpedient or improper in priests. The respectability of their office, and the honor of religion, required unblemished sanctity in their families as well as themselves, and departures from it in their case were visited with severer punishment than in that of others.

10-15. he that is the high priest among his brethren . . . shall not uncover his head, nor rend his clothes--The indulgence in the excepted cases of family bereavement, mentioned above [ Leviticus 21:2 Leviticus 21:3 ], which was granted to the common priests, was denied to him; for his absence from the sanctuary for the removal of any contracted defilement could not have been dispensed with, neither could he have acted as intercessor for the people, unless ceremonially clean. Moreover, the high dignity of his office demanded a corresponding superiority in personal holiness, and stringent rules were prescribed for the purpose of upholding the suitable dignity of his station and family. The same rules are extended to the families of Christian ministers ( 1 Timothy 3:2 , Titus 1:6 ).

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 ( Hebrews 7:26 ).
