John Gill Commentary Isaiah 24:14

"These shall lift up their voice, they shall shout; for the majesty of Jehovah they cry aloud from the sea." — Isaiah 24:14 (ASV)

They shall lift up their voice, they shall sing
That is, as the Septuagint version adds, ``they that are left upon the earth;'' these shall lift up their voice, in singing the praises of God, for his judgments on Babylon, and avenging the blood of his saints; and for their deliverance and salvation, and the inestimable blessings they are now put into the possession of; these are they, who, having gotten the victory over the beast and his image, sing the song of Moses and the Lamb, (Revelation 15:2Revelation 15:3) (Revelation 19:1Revelation 19:2) :

for the majesty of the Lord, they shall cry aloud from the sea :
so the Hebrew accents distinguish these clauses; and the sense is, that from the west, as Kimchi and Ben Melech interpret it, from the western nations, where Protestantism chiefly prevails; or from the Mediterranean Sea, which lay west of Judea; from the maritime countries, the countries bordering upon it, where at this time will appear many that will embrace the Gospel of Christ; or from the isles of the sea, as the phrase is explained in the next verse (Isaiah 24:15) , such as our isles of Great Britain and Ireland; great acclamations will be made unto the Lord, on account of his glorious majesty, seen in the destruction of antichrist, and in setting up his own kingdom and glory:

these are the four and twenty elders, who will fall down, and give thanks to Christ, for taking to himself his great power, and reigning; and these triumphant and victorious persons are represented as standing on a sea, while they make their shouts and hallelujahs; see (Revelation 11:16–18) (15:2)

this, with what follows in the two next verses (Isaiah 24:15Isaiah 24:16) , belong to the Philadelphian church state, or spiritual reign of Christ, and express the light and joy that will attend that.
