John Gill Commentary Zechariah 2:13

"Be silent, all flesh, before Jehovah; for he is waked up out of his holy habitation." — Zechariah 2:13 (ASV)

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 (Psalms 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.
