It was before appointed that the priests should teach the people the statutes God had given concerning the difference between clean and unclean, Lev 10:10, Lev 10:11. Now here it is provided that they should themselves observe what they were to teach the people. Note, Those whose office it is to instruct must do it by example as well as precept, Ti1 4:12. The priests were to draw nearer to God than any of the people, and to be more intimately conversant with sacred things, and therefore it was required of them that they should keep at a greater distance than others from every thing that was defiling and might diminish the honour of their priesthood.

I.They must take care not to disparage themselves in their mourning for the dead. All that mourned for the dead were supposed to come near the body, if not to touch it: and the Jews say, "It made a man ceremonially unclean to come within six feet of a dead corpse;" nay, it is declared (Num 19:14) that all who come into the tent where the dead body lies shall be unclean seven days. Therefore all the mourners that attended the funeral could not but defile themselves, so as not to be fit to come into the sanctuary for seven days: for this reason it is ordered, 1. That the priests should never put themselves under this incapacity of coming into the sanctuary, unless it were for one of their nearest relations, Lev 21:1-3. A priest was permitted to do it for a parent or a child, for a brother or an unmarried sister, and therefore, no doubt (though this is not mentioned) for the wife of his bosom; for Ezekiel, a priest, would have mourned for his wife if he had not been particularly prohibited, Eze 24:17. By this allowance God put an honour upon natural affection, and favoured it so far as to dispense with the attendance of his servants for seven days, while they indulged themselves in their sorrow for the death of their dear relations; but, beyond this period, weeping must not hinder sowing, nor their affection to their relations take them off from the service of the sanctuary. Nor was it at all allowed for the death of any other, no, not of a chief man among the people, as some read it, Lev 21:4. They must not defile themselves, no, nor for the high priest himself, unless thus akin to them. Though there is a friend that is nearer than a brother, yet the priests must not pay this respect to the best friend they had, except he were a relation, lest, if it were allowed for one, others should expect it, and so they should be frequently taken off from their work: and it is hereby intimated that there is a particular affection to be reserved for those that are thus near akin to us; and, when any such are removed by death, we ought to be affected with it, and lay it to heart, as the near approach of death to ourselves, and an alarm to us to prepare to follow. 2. That they must not be extravagant in the expressions of their mourning, no, not for their dearest relations, Lev 21:5. Their mourning must not be either, (1.) Superstitious, according to the manner of the heathen, who cut off their hair, and let out their blood, in honour of the imaginary deities which presided (as they thought) in the congregation of the dead, that they might engage them to be propitious to their departed friends. Even the superstitious rites used of old at funerals are an indication of the ancient belief of the immortality of the soul, and its existence in a separate state: and though the rites themselves were forbidden by the divine law, because they were performed to false gods, yet the decent respect which nature teaches and which the law allows to be paid to the remains of our deceased friends, shows that we are not to look upon them as lost. Nor, (2.) Must it be passionate or immoderate. Note, God's ministers must be examples to others of patience under affliction, particularly that which touches in a very tender part, the death of their near relations. They are supposed to know more than others of the reasons why we must not sorrow as those that have no hope (Th1 4:13), and therefore they ought to be eminently calm and composed, that they may be able to comfort others with the same comforts wherewith they are themselves comforted of God. The people were forbidden to mourn for the dead with superstitious rites (Lev 19:27, Lev 19:28), and what was unlawful to them was much more unlawful to the priest. The reason given for their peculiar care not to defile themselves we have (Lev 21:6): Because they offered the bread of their God, even the offerings of the Lord made by fire, which were the provisions of God's house and table. They are highly honoured, and therefore must not stain their honour by making themselves slaves to their passions; they are continually employed in sacred service, and therefore must not be either diverted from or disfitted for the services they were called to. If they pollute themselves, they profane the name of their God on whom they attend: if the servants are rude and of ill behaviour, it is a reflection upon the master, as if he kept a loose and disorderly house. Note, All that either offer or eat the bread of our God must be holy in all manner of conversation, or else they profane that name which they pretend to sanctify.

II.They must take care not to degrade themselves in their marriage, Lev 21:7. A priest must not marry a woman of ill fame, that either had been guilty or was suspected to have been guilty of uncleanness. He must not only not marry a harlot, though ever so great a penitent for her former whoredoms, but he must not marry one that was profane, that is, of a light carriage or indecent behaviour. Nay, he must not marry one that was divorced, because there was reason to think it was for some fault she was divorced. The priests were forbidden to undervalue themselves by such marriages as these, which were allowed to others, 1. Lest it should bring a present reproach upon their ministry, harden the profane in their profaneness, and grieve the hearts of serious people: the New Testament gives laws to ministers' wives (Ti1 3:11), that they be grave and sober, that the ministry be not blamed. 2. Lest it should entail a reproach upon their families; for the work and honour of the priesthood were to descend as an inheritance to their children after them. Those do not consult the good of their posterity as they ought who do not take care to marry such as are of good report and character. He that would seek a godly seed (as the expression is, Mal 2:15) must first seek a godly wife, and take heed of a corruption of blood. It is added here (Lev 21:8), Thou shalt sanctify him, and he shall be holy unto thee. "Not only thou, O Moses, by taking care that these laws be observed, but thou, O Israel, by all endeavours possible to keep up the reputation of the priesthood, which the priests themselves must do nothing to expose or forfeit. He is holy to his God (Lev 21:7), therefore he shall be holy unto thee." Note, We must honour those whom our God puts honour upon. Gospel ministers by this rule are to be esteemed very highly in love for their works' sake (Th1 5:13), and every Christian must look upon himself as concerned to be the guardian of their honour.

III.Their children must be afraid of doing any thing to disparage them (Lev 21:9): If the daughter of any priest play the whore, her crime is great; she not only polluteth but profaneth herself: other women have not that honour to lose that she has, who, as one of a priest's family, has eaten of the holy things, and is supposed to have been better educated than others. Nay, she profaneth her father; he is reflected upon, and every body will be ready to ask, "Why did not he teach her better?" And the sinners in Zion will insult and say, "Here is your priest's daughter." Her punishment there must be peculiar: She shall be burnt with fire, for a terror to all priests' daughters. Note, The children of ministers ought, of all others, to take heed of doing any thing that is scandalous, because in them it is doubly scandalous, and will be punished accordingly by him whose name is Jealous.

That is a whore - A prostitute, though even reclaimed.

Profane - A heathen, or one who is not a cordial believer in the true God. Put away from her husband - Because this very circumstance might lead to suspicion that the priest and the divorced woman might have been improperly connected before.

Thou shalt sanctify him therefore,.... In thought and word, as Aben Ezra, by thinking and speaking well of him; should esteem and reckon him a holy person, being in a sacred office, and honour him as such; and do all that can be done to preserve him from unholiness and impurity, and particularly from marrying with improper and unsuitable persons, such as would bring a scandal on him and his sacred office: this seems to be spoken to Moses, and so to the civil magistrate in succession, who were not to suffer such marriages to take place in the priesthood; and were not only to persuade from it, but to exercise their authority, and oblige them to put away such wives, and if they refused, to use severity; so Jarchi,""thou shalt sanctify him", whether he will or not; if he will not put her away, beat him and chastise him until he does put "her away",''see Ezr 2:62,

for he offereth the bread of the Lord; meaning not the shewbread he set in order before the Lord every week, but the various gift and sacrifices which were offered to God by him, and were acceptable to him as his food; and therefore he ought to be holy that drew nigh to God, and was employed in such service, see Lev 21:6,

he shall be holy unto thee; in thy account and estimation, and for thy service to offer holy sacrifices, and therefore should be careful of his holiness to preserve it:

for I the Lord, which sanctify you, am holy; in his nature, works, and ways, and who had separated them from all other people to be a holy people to him, and therefore they that ministered in holy things for them should be holy likewise.

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.
