When the days were fulfilled Leitourgia is employed by Luke to denote a charge or office, which passed, as we have said, to each of them in regular order, (1 Chronicles 24:3.) We are told that, when the time of his office had expired, Zacharias returned home. Hence we conclude that, so long as the priests were attending in their turns, they did not enter their own houses, that they might be entirely devoted and attached to the worship of God. For this purpose galleries were constructed around the walls of the temple, in which they had "chambers," (1 Kings 6:5.) The law did not, indeed, forbid a priest to enter his house, but, as it did not permit those who ate the show-bread to come near their wives, (1 Samuel 21:4,) and as many persons were disposed to treat sacred things in an irreverent manner, this was probably discovered to be a remedy, that, being removed from all temptations, they might preserve themselves pure and clear from every defilement. And they were not only discharged from intercourse with their wives, but from the use of wine and every kind of intoxicating drink, (Leviticus 10:9.) While they were commanded to change their mode of living, it was advantageous for them not to depart from the temple, that the very sight of the place might remind them to cultivate such purity as the Lord had enjoined. It was proper also to withdraw every means of gratification, that they might devote themselves more unreservedly to their office. The Papists of the present day employ this as a pretense for defending the tyrannical law of celibacy. They argue thus. The priests were formerly enjoined to withdraw from their wives, while they were engaged in religious services. Most properly is perpetual continence now demanded from the priests, who not in their turn, but every day, offer sacrifices; more especially since the importance of religious services is far higher than it was under the law. But I should like to know why they do not also abstain from wine and strong drink. For we are not at liberty to separate commandments which God has joined, so as to keep the one half and disregard the other. Intercourse with wives is not so expressly forbidden as the drinking of wine, (Ezekiel 44:21.) If, under the pretense of the law, the Pope enjoins celibacy on his priests, why does he allow them wine? Nay, on this principle, all priests ought to be thrown into some retired apartments of the churches, to pass their whole life immured in prisons, and excluded from the society of women and of the people. It is now abundantly clear that they wickedly shelter themselves under the law of God, to which they do not adhere. But the full solution of the difficulty depends on the distinction between the law and the gospel. A priest stood in the presence of God, to expiate the sins of the people, to be, as it were, a mediator between God and men. He who sustained that character ought to have had something peculiar about him, that he might be distinguished from the common rank of men, and recognised as a figure of the true Mediator. Such, too, was the design of the holy garments and the anointing. In our day the public ministers and pastors of the church have nothing of this description. I speak of the ministers whom Christ has appointed to feed his flock, not of those whom the Pope commissions, as executioners rather than priests, to murder Christ. Let us therefore rest in the decision of the Spirit, which pronounces that "marriage is honorable in all," (Hebrews 13:4.)

As soon as the days of his ministration - As soon as he had fulfilled the duties of the week. It might have been supposed that the extraordinary occurrence in the temple, together with his own calamity, would have induced him at once to leave this place and return home; but his duty was in the temple. His piety prompted him to remain there in the service of God. He was not unfitted for burning incense by his dumbness, and it was not proper for him to leave his post. It is the duty of ministers of religion to remain at their work until they are unfitted for it, and unable to serve God in their profession. Then they must retire. But until that time, he that for trifling causes forsakes his post is guilty of unfaithfulness to his Master.

As soon as the days of his ministration were accomplished - Each family of the priesthood officiated one whole week, 2-Kings 11:17.
There is something very instructive in the conduct of this priest; had he not loved the service he was engaged in, he might have made the loss of his speech a pretext for immediately quitting it. But as he was not thereby disabled from fulfilling the sacerdotal function, so he saw he was bound to continue till his ministry was ended; or till God had given him a positive dismission. Preachers who give up their labor in the vineyard because of some trifling bodily disorder by which they are afflicted, or through some inconvenience in outward circumstances, which the follower of a cross-bearing, crucified Lord should not mention, show that they either never had a proper concern for the honor of their Master or for the salvation of men, or else that they have lost the spirit of their Master, and the spirit of their work. Again, Zacharias did not hasten to his house to tell his wife the good news that he had received from heaven, in which she was certainly very much interested: the angel had promised that all his words should be fulfilled in their season, and for this season he patiently waited in the path of duty. He had engaged in the work of the Lord, and must pay no attention to any thing that was likely to mar or interrupt his religious service. Preachers who profess to be called of God to labor in the word and doctrine, and who abandon their work for filthy lucre's sake, are the most contemptible of mortals, and traitors to their God.

And it came to pass, that as soon as the days of his ministration,.... In the order of the course, which might be three, four, five, or six days, according to the number of the heads of the house of their fathers in the course; See Gill on Luke 1:5.
were accomplished: for though he was deaf and dumb, he was not hereby disqualified for service. Deafness and dumbness excused persons from various duties (s) but did not disqualify priests: a Levite, if he had lost his voice, was disqualified, but not a priest; (t) the reason was this, because it was one part of the work of the Levites to sing, and therefore could not perform it without a voice; but such was the work of the priests, that though deaf and dumb, they could discharge it; as cleansing the altar, trimming the lamps, carrying the parts to the altar, laying them upon it, and burning them, or offering any sacrifice, burning incense, &c. which was the business of Zacharias; which when he had fulfilled, he departed to his own house; which was not at Jerusalem, but in the hill country, in a city of Judah there; see Luke 1:39.
