Here is a sealing of the whole prophecy. The Prophet highly extols the power of God, that the Jews might not still doubt or fear as with regard to things uncertain. He says that whatever he had hitherto declared was indubitable; for God would put forth his power to succor his Church and to remove whatever hindrance there might be. We have seen similar expressions elsewhere, that is, in the second chapter of Habakkuk and in the first of Zephaniah; (Habakkuk 2:1 Zephaniah 1:1) and these Prophets had nearly the same object in view; for Habakkuk, after having spoken of the restoration of the people, thus concludes, -- that God was coming forth to bid silence to all nations, that no one might dare to oppose when it was his will to redeem his Church. So also Zephaniah, after having, described the slaughter of God's enemies, when God ordered sacrifices to be made to him as it were from the whole world, uses the same mode of expression, as though he had said, that there would be nothing to resist the power of God. It is the same here, Silent, he says, let all flesh be before Jehovah. It is, in short, the shout of triumph, by which Zechariah exults over all the enemies of the Church, and shows that they would rage in vain, as they could effect nothing, however clamorous they might be. By silence we are to understand, as elsewhere observed, submission. The ungodly are not indeed silent before God, so as willingly to obey his word, or reverently to receive what he may bid or command, or humbly to submit under his powerful hand; for these things are done only by the faithful. Silence, then, is what especially belongs to the elect and the faithful; for they willingly close their mouth to hear God speaking. But the ungodly are also said to be silent, when God restrains their madness: and how much soever they may inwardly murmur and rage, they yet cannot openly resist; so that he completes his work, and they are at length made ashamed of the swelling, words they have vomited forth, when they pass off in smoke. This is the sense in which the Prophet says now, silent be all flesh. He means, in short, by these words, That when God shall go forth to deliver his Church, he will be terrible; so that all who had before furiously assailed his chosen people, shall be constrained to tremble. With regard to the habitation of holiness, I explain it of the temple rather than of heaven. I indeed allow that heaven is often thus called in Scripture: and it is called the palace or temple of God, for we cannot think as we ought of God's infinite glory, except we are carried above the world. This is the reason why God says that he dwells in heaven. But as the Church is spoken of here, Zechariah, I doubt not, means the temple. It is indeed certain that there was no temple when God began to rise as one awakened from sleep, to restore his people: but as the faithful are said in Psalm 102 to pity the dust of Sion, because the place continued sacred even in its degradation and ruin; so also in this passage Zechariah says, that God was roused -- Whence? from Sion, from that despised place, exposed to the derision of the ungodly: yet there God continued to dwell, that he might build again the temple, where his name was to be invoked until Christ appeared. We now see that the temple or Sion is intended rather than heaven, when all circumstances are duly weighed. Now follows --

Be silent - Literally, "hush all flesh, before the Lord" (see at Habakkuk 2:20, p. 207); man in his weakness Genesis 6:3; 2-Chronicles 32:8; Job 10:4; Psalm 56:4; Psalm 78:39; Isaiah 31:3; Jeremiah 17:5, "flesh and blood" in the language of the New Testament Matthew 16:17; 1-Corinthians 15:50; Galatians 1:16, before God his Maker. "All flesh," the whole human race Genesis 6:12; Psalm 65:3; Psalm 145:21; Isaiah 40:5-6; Isaiah 49:26; Isaiah 66:23; Joel 3:1; Ezekiel 21:4, Ezekiel 21:9-10, is to be hushed before God, because His judgments, as His mercies, are over all.
For God ariseth - God seemeth to be quiescent, as it were, when He bears with us; to arise, when He puts forth His power, either for us, when we pray, "Lord, awake to help me" (Psalm 59:4, add Psalm 7:7; Psalm 44:24); or in displeasure. His "holy habitation" is alike the tabernacle 1-Samuel 2:29, 1-Samuel 2:32; Psalm 26:9; Psalm 68:6, temple 2-Chronicles 36:15, heaven Deuteronomy 26:15; Jeremiah 25:30; 2-Chronicles 30:27, since His presence is in all.

Be silent, O all flesh - Let all the nations of the world be astonished at this. God will arise, and deliver this ancient people, and bring them into the glorious liberty of the sons of God.

Be silent, O all flesh, before the Lord,.... Be filled with fear, awe, and astonishment, at the wonderful work of God; the destruction of antichrist; the conversion of the Jews, and the calling of the Gentiles: let them not open their mouths, or dare to say one word against it. The Targum interprets the words of the wicked, and paraphrases them thus,
"let all the wicked be consumed before the Lord;''
see Psalm 104:35 and it seems to design the rest of the people, who will not be converted; called flesh, being not only frail and mortal, but corrupt and sinful; and so not able to contend with God, who is mighty in strength, and glorious in holiness, and a God doing wonders. A like phrase is in Habakkuk 2:20,
for he is raised up out of his holy habitation: which is heaven, Isaiah 63:15 where he seemed to have been as it were asleep for many hundreds of years, even during the reign of antichrist; but now he will be as a man awaked out of his sleep, and will arise to take vengeance on his and his church's enemies, and to help them, and make them happy and glorious.

Be silent, O all flesh-- (Habakkuk 2:20). "Let all in silent awe and reverence await the Lord's coming interposition in behalf of His people!" The address is both to the Gentile foes, who prided themselves on their power as if irresistible, and to the unbelieving Jews, who distrusted God's promises as incredible. Three reasons why they must be silent are implied: (1) they are but "flesh," weak and ignorant; (2) He is JEHOVAH, all-wise and all-powerful; (3) He is already "raised up out of His place," and who can stand before Him? [PEMBELLUS], (Psalm 76:8-9).
he is raised up out of his holy habitation--that is, out of heaven (Deuteronomy 26:15; 2-Chronicles 30:27; Isaiah 63:15), to judge and avenge His people (Isaiah 26:21); or, "out of His holy" temple, contemptible and incomplete as it looked then when Zechariah urged them to rebuild it [CALVIN]. But the call to all to "be silent" is rather when God has come forth from heaven where so long He has dwelt unseen, and is about to inflict vengeance on the foe, before taking up His dwelling in Zion and the temple. However, Psalm 50:1-2 ("Out of Zion"), Psalm 50:3 (compare Habakkuk 2:3), Psalm 50:4, favors CALVIN'S view. God is now "silent" while the Gentile foe speaks arrogance against His people; but "our God shall come and no longer keep silence"; then in turn must all flesh "be silent" before Him.

Be silent - Reverence and adore God, and expect the accomplishment of his word. All flesh - Both Jew and Gentile. He is raised up - God is on this work already, and he will not sit down again, 'till he has accomplished his whole work.
