{p} Then the moon shall be confounded, and the sun ashamed, when the LORD of hosts shall reign on mount Zion, and in Jerusalem, and before his ancients gloriously.

(p) When God restores his Church, the glory of it will so shine, and his ministers (who are called his ancient men) that the sun and the moon will be dark in comparison to it.

Wesley's Notes

24:23 The sun - All earthly powers and glories shall be obscured with the far greater splendor of Christ, the king of kings, at whose feet even the kings of the earth shall fall down and worship. The Lord - The Messiah, who, tho' man, yet is also God, and the Lord of hosts. Shall reign - Shall come in the flesh, and set up his kingdom, first in Jerusalem, and afterward in all other nations. Before - Before his ministers, who are in some sort the courtiers of the King of Glory. But the ancients are here put for the whole church, in whose name and for whose service they act.

Matthew Henry's Concise Commentary

24:16-23 Believers may be driven into the uttermost parts of the earth; but they are singing, not sighing. Here is terror to sinners; the prophet laments the miseries he saw breaking in like a torrent; and the small number of believers. He foresees that sin would abound. The meaning is plain, that evil pursues sinners. Unsteady, uncertain are all these things. Worldly men think to dwell in the earth as in a palace, as in a castle; but it shall be removed like a cottage, like a lodge put up for the night. It shall fall and not rise again; but there shall be new heavens and a new earth, in which shall dwell nothing but righteousness. Sin is a burden to the whole creation; it is a heavy burden, under which it groans now, and will sink at last. The high ones, that are puffed up with their grandeur, that think themselves out of the reach of danger, God will visit for their pride and cruelty. Let us judge nothing before the time, though some shall be visited. None in this world should be secure, though their condition be ever so prosperous; nor need any despair, though their condition be ever so deplorable. God will be glorified in all this. But the mystery of Providence is not yet finished. The ruin of the Redeemer's enemies must make way for his kingdom, and then the Sun of Righteousness will appear in full glory. Happy are those who take warning by the sentence against others; every impenitent sinner will sink under his transgression, and rise no more, while believers enjoy everlasting bliss.
