(15) Neither shall he profane his seed.—Better, And he shall not profane; that is, he is not to contract any of these forbidden marriages, lest he should thereby degrade his offspring, since the children of such an issue, as well as their mother, were debarred the privileges of the priesthood, and were not permitted to partake of those portions of the sacrifices which formed the perquisites of the officiating priests.

Leviticus 21:15. I the Lord sanctify him — I have separated him from all other men for my immediate service, and therefore will not have that race corrupted.

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.Profane his seed - i. e. by a marriage which was not in keeping with the holiness of his office. 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 [Le 21:2, 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 (1Ti 3:2; Tit 1:6). Neither shall he profane his seed by mixing it with forbidden kinds, whereby the children would be disparaged, and rendered unfit for their priestly function.

Do sanctify him, i.e. have separated him from all other sorts of men for my especial and immediate service, and therefore will not have that race corrupted.

Neither shall he profane his seed among his people,.... By marrying any such persons, whereby his children, born of them, would lie under disgrace, and be unfit to succeed him in the priesthood, or by marrying among mean persons, or by marrying them to such as were unlawful, and would be a disparagement to them:

for I the Lord do sanctify him; separate him from all others, to the high and sacred office of the high priesthood, and am concerned for his honour and holiness; and therefore it became him to observe these laws and rules, and abstain from such disagreeable marriages.

Neither shall he profane his {l} seed among his people: for I the LORD do sanctify him.

(l) By marrying any unchaste or defamed woman.
