(13) Thy prayer is heard.--The words imply a prayer on the part of Zacharias, not that he might have a son (that hope appears to have died out long before), but that the Kingdom of God might come. Praying for this he receives more than he asks, and the long yearning of his soul for a son who might bear his part in that Kingdom is at last realised.

Thou shalt call his name John.--The English monosyllable represents the Greek Joannes, the Hebrew Jochanan. The name appears as belonging to the men of various tribes (1Chronicles 3:15; Ezra 8:12; Jeremiah 41:11). As the meaning of the Hebrew word is "Jehovah is gracious," the announcement of the name was in itself a pledge of the outpouring of the grace of God.

Verse 13. - Thy prayer is heard. What was the nature of this prayer? The Greek word (δεήσις) used here implies that some special supplication had been offered, and which the angel tells had been listened to at the throne of grace. The righteous old man had not, as some have thought, been praying for a son, - he had long resigned himself in this private sorrow to the will of his God; but we may well suppose that on that solemn occasion he prayed the unselfish patriotic prayer that the long looked for Messiah would hasten his coming. His name John; the shortened form for Jehochanan, "the grace of Jehovah." Under various diminutives, such as Jonah, it was a favorite Hebrew name.

1:5-25 The father and mother of John the Baptist were sinners as all are, and were justified and saved in the same way as others; but they were eminent for piety and integrity. They had no children, and it could not be expected that Elisabeth should have any in her old age. While Zacharias was burning incense in the temple, the whole multitude of the people were praying without. All the prayers we offer up to God, are acceptable and successful only by Christ's intercession in the temple of God above. We cannot expect an interest therein if we do not pray, and pray with our spirits, and are not earnest in prayer. Nor can we expect that the best of our prayers should gain acceptance, and bring an answer of peace, but through the mediation of Christ, who ever lives, making intercession. The prayers Zacharias often made, received an answer of peace. Prayers of faith are filed in heaven, and are not forgotten. Prayers made when we were young and entering into the world, may be answered when we are old and going out of the world. Mercies are doubly sweet that are given in answer to prayer. Zacharias shall have a son in his old age, who shall be instrumental in the conversion of many souls to God, and preparing them to receive the gospel of Christ. He shall go before Him with courage, zeal, holiness, and a mind dead to earthly interests and pleasures. The disobedient and rebellious would be brought back to the wisdom of their righteous forefathers, or rather, brought to attend to the wisdom of that Just One who was coming among them. Zacharias heard all that the angel said; but his unbelief spake. In striking him dumb, God dealt justly with him, because he had objected against God's word. We may admire the patience of God towards us. God dealt kindly with him, for thus he prevented his speaking any more distrustful, unbelieving words. Thus also God confirmed his faith. If by the rebukes we are under for our sin, we are brought to give the more credit to the word of God, we have no reason to complain. Even real believers are apt to dishonour God by unbelief; and their mouths are stopped in silence and confusion, when otherwise they would have been praising God with joy and gratitude. In God's gracious dealings with us we ought to observe his gracious regards to us. He has looked on us with compassion and favour, and therefore has thus dealt with us.But the angel said unto him, fear not, Zacharias,.... He calls him by his name; for holy men are known to angels in person, and by name; to whom they are ministering spirits, and for whose good they are concerned; and bid him not be afraid, as the angel also said to the women at Christ's sepulchre, Matthew 28:5 for he saw by his countenance and gestures, that he was greatly surprised and terrified at the sight of him:

for thy prayer is heard; which he had many years ago put up for a son; for it cannot be thought that he had been now praying for one, being in such an advanced age, and having for years past given up all hopes of one, and was even unbelieving, when he was told by the angel he should have one: prayer is sometimes immediately heard, and answered; and sometimes an answer is deferred a long time, to try the faith and patience of the saints, and to discover the more the wisdom, power, and goodness of God: or this may have regard to his present prayer, one branch of which might concern the coming of the Messiah, which was now expecting, and therefore is told, that his prayer was heard; since the angel that appeared to him, brought him the news of the conception and birth of his forerunner:

and thy wife Elisabeth shall bear thee a son; who had been always barren, and was called so, Luke 1:7.

And thou shalt call his name John; in Hebrew, "Jochanan", and signifies "gracious": a fit name for one that was filled with the gifts and graces of the Spirit; and was the harbinger of the Messiah, who is full of grace and truth; and the ushered in the Messiah's kingdom, which is a dispensation of grace.
