Luke 1:20

So, because you do not believe, you will be deaf and unable to speak. Justly he is subjected to both—deafness and muteness—for as one who disobeyed he is punished with deafness, and as one who contradicted, with silence. Moreover, he also prefigured what happened with …

But he gives him the sign which he asks for, that he who spoke in unbelief, might now by silence learn to believe; as it follows; and, behold, thou shall be dumb.

But he who pretends not to believe what he has heard is punished with the penalty of silence, because he is mute who does not understand the spiritual sense within the letters. Nor does such a one know how to give words to the people …

(cap. i.) Because the word in the Greek (κωφὸς) may also signify deaf, he well says, Because thou believest not, thou shalt be deaf, and shalt not be able to speak. For most reasonably he suffered these two things; as disobedient, he incurs the penalty of deafness; as an objector, of silence.

And behold, you shall be silent, etc. Here is touched upon the sign of authority, and he gives a sign of penalty on account of the vice of unbelief. He therefore sets forth the sign of silence up to the appointed time, until the day …

If thou wilt have a sign for the support of thy faith, it shall be such a one as shall be also the punishment of thine unbelief; thou shalt not be able to speak till the day that these things shall be performed, "

Thou shalt be both dumb and deaf; the same word signifies both, and it is plain that he lost his hearing as well as his speech, for his friends made signs to him (

And behold, thou shalt be dumb, &c. Or "silent; and not able to speak", if he would.

Thou shalt be dumb - Σιωπων silent; this translation is literal; the angel immediately explains it, thou shalt not be able to speak. Dumbness ordinarily proceeds from a natural imperfection or debility of the organs of speech; in this case there was no natural weakness or unfitness in those organs; but, for his rash and unbelieving speech, silence is imposed upon him by the Lord, and he shall not be able to break it, till the power that has silenced him gives him again the permission to speak!

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.

UNBELIEF is everywhere a great sin, and a grievous mistake. Unbelief has proved the ruin of those countless multitudes who, having heard the gospel, rejected it, died in their sins, have been consigned to the place of torment, and await the fiercer judgment of the last day. I might ask the question concerning this innumerable host, "Who slew all these?" The answer would be, "Unbelief." And when unbelief comes into the Christian's heart, as it does at times—for the truest believer has his times of doubt; even Abraham, the father of the faithful, sometimes had his misgivings—that unbelief does not assail his thoughts without withering his joys, and impairing his energies. There is nothing in the world that costs a saint so dear as doubt. If he disbelieve his God, he most assuredly robs himself of comfort, deprives himself of strength, and does himself a real injury. The case of Zacharias may be a, lesson to the Lord's people. It is to them I am going to speak: Zacharias is a striking example of the ills a good man may have to suffer as the result of his unbelief. In reviewing these, we mark:— I. THE CHARACTER AND POSITION OF ZACHARIAS. Here we cannot fail to discover some profitable lesson. He was undoubtedly a believer. He is said, in the sixth verse, to have been righteous before God. No man ever obtained such a reputation except by faith. "The just shall live by faith." No other righteousness than that which is faith is of any esteem in God's account. Such was the righteousness of Abraham, and such was the righteousness of all the saints before the advent of our Redeemer. Such, too, has been the standard ever since. Zacharias evidently was a real believer. Yet for all that, when the angel appeared to him, and God gave him the promise of a son, he was amazed, bewildered, incredulous, and could not credit, but only question the announcement.

Because thou believest not ... - This was both a sign and a judgment - a sign that he had come from God, and that the thing would be fulfilled: and a judgment for not giving credit to what he had said. There is no sin in the sight of God more aggravated than unbelief. When God speaks; man should believe; nor can he that “will not” believe escape punishment. God speaks only truth, and we should believe Him. God speaks only what is for our good, and it is right that we should suffer if we do not credit what He says.
