Luke 1:23

Therefore first mutual cohabitation is indicated, when he says: And it came to pass, when the days of his office were fulfilled, he went to his house, namely to cohabit and to render the debt to his wife; whence Chrysostom says that on the same …

Note also that Zacharias did not go to his house until the days of his service were completed, but remained in the temple. For the hill country was indeed far from Jerusalem. And a priest, even if he had a house in Jerusalem itself, was …

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 Luk 1:5. were accomplished: for though he was deaf and dumb, he was not hereby disqualified for service.

We see in this passage, the power of unbelief in a holy man. As righteous and holy as Zachariah was — the announcement of the angel appeared unbelievable to him. He could not think it possible that an old man like himself could have a son. "How shall I know this?" he says, "for I am an old man, and my wife well along in years." A well-instructed Jew, like Zachariah, ought not to have raised such a question. No doubt he was well acquainted with the Old Testament Scriptures. He ought to have remembered the astonishing births of Isaac , and Samson , and Samuel in old times. He ought to have remembered that what God has done once — He can do again; and that with Him, nothing is impossible. But he forgot all this. He thought of nothing but the arguments of mere human reasoning. In the same way, it often happens in religious matters, that where human reasoning begins — faith ends. Let us learn in wisdom from the fault of Zachariah. It is a fault to which God's people in every age have been sadly liable. The histories of Abraham, and Isaac, and Moses, and Hezekiah, and Jehoshaphat — will all show us that a true believer may sometimes be overtaken by unbelief . Unbelief is one of the first corruptions which came into man's heart in the day of the fall, when Eve believed the devil rather than God. Unbelief is one of the most deep-rooted sins by which a saint is plagued, and from which he is never entirely freed until he dies. Let us pray daily, "Lord increase my faith!" Let us not doubt that when God says a thing — that thing shall be fulfilled. We see furthermore, in these verses — the privilege and portion of God's angels. They carry messages to God's people. They enjoy God's immediate presence.
