(8) Thou shalt sanctify him therefore.--This is addressed to the Jewish community. They are to take care that the priest does not contract such illegal marriages, and to sanctify him only who acts in obedience to these statutes. The Jewish priest is thus placed under the supervision of the people. His sacred office, and his duly performing the priestly functions. are their concern. If he refused to conform to the law of sanctity, the people, according to the administrators of the Law during the second Temple, were to compel him to do so by the penalty of administering to him the prescribed number of stripes.

He shall be holy unto thee.--On the other hand, when he acts in accordance with his sacred office, the people must reverence his holy person. Hence the administrators of the Law during the second Temple enacted that the priest is to take precedence on public occasions. Thus, when the people assemble, he opens the meeting by invoking God's blessing. At the reading of the Law of God in the synagogue, he is called up first to the rostrum to read the first portion, and at table he recites the benedictions over the repast. This honour the Jews assign to the priests to this day.

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.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 Ezra 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 Leviticus 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.
