Isaiah 24:23
21 At that time the Lord will punish the heavenly forces in the heavens and the earthly kings on the earth. 22 They will be imprisoned in a pit, locked up in a prison, and after staying there for a long time, they will be punished. 23 The full moon will be covered up, the bright sun will be darkened; for the Lord of Heaven’s Armies will rule on Mount Zion in Jerusalem in the presence of his assembly, in majestic splendor.
LXX Isaiah 24:23
21 And God will bring his hand against the ornament of heaven and against the kings of the earth. 22 And they will gather them together and shut them up in a fortress and in a prison; through many generations will be their visitation. 23 Then the brick will be dissolved, and the wall will fall, because the Lord will reign in Sion and in Ierousalem, and before the elders he will be glorified.
Notes and References
"... When the content of the reconstructed vocalization differs significantly from that of the Masoretic text, and when the reconstruction is supported by identical equivalents elsewhere in the LXX, as a rule, the reconstruction is reliable ... (Isaiah 24:23; Jeremiah 2:34; Jeremiah 6:15; Jeremiah 13:19) ... Reconstructed vocalizations that are preferable to the Masoretic text. If the internal criteria in favor of the vocalization underlying the LXX are convincing, that vocalization must have been original. Naturally, all arguments based on internal evidence are subjective ..."
