Charles Ellicott Commentary Isaiah 24:23

"Then the moon shall be confounded, and the sun ashamed; for Jehovah of hosts will reign in mount Zion, and in Jerusalem; and before his elders shall be glory." — Isaiah 24:23 (ASV)

The moon shall be confounded ... —The thought implied is that the most glorious forms of created light will become dim, the moon red as with the blush of shame, the sun turning pale, before the glory of Jehovah’s presence.

The Lord of hosts shall reign ... —Better, has become king, the phrase being that used as in 2 Samuel 5:4; 1 Kings 15:1, for a king’s accession to his throne.

And before his ancients gloriously. —Better, and before his elders he shall glory. The “elders” are, like the seventy of Exodus 24:9, like the twenty-four of Revelation 4:4, the chosen ones of the new Jerusalem, to whom it shall be given, as the counselors of the great King, to see His glory, that glory resting on them as in old times it rested upon Moses.
