Isaiah 13:6

"Wail ye; for the day of Jehovah is at hand; as destruction from the Almighty shall it come. Therefore shall all hands be feeble, and every heart of man shall melt: and they shall all be dismayed; pangs and sorrow shall take hold of them; they shall be in pain as a woman in travail: they shall look in amazement one at another; and their faces shall be faces of flame."

"The Almighty ..." The Hebrew has the word [~Shaddai] for "The Almighty" in this passage. "This word is used frequently in the Pentateuch; it is not often found in the prophets; and, when it occurs, the severe and awful aspect of God's divine nature is the more prominent."[8]

"The day of Jehovah ..." (Isaiah 13:6,9) in the Old Testament often refers to the eternal judgment scheduled to come at the end of the Christian dispensation; although, in the prophets, there were predicted many "days of Jehovah," all of them typical of the Day of Judgment and resulting in the destruction of a succession of wicked cities and civilizations. The specific mention of Babylon in this passage is very significant, because it indicates that Babylon would be in some special way an archetype of human rebellion against God. Therefore we have overtones in this chapter of the "Mystery Babylon the Great" in the prophecy of Revelation.

The primary reference here, of course, "is to the events of 539 B.C.";[9] but this fall of Babylon is prophetically typical of the fall of the latter-day Babylon (Revelation 14:8). As we proceed in this chapter, we shall see that far more than the mere fall of ancient Babylon was here prophesied, especially, the total, permanent desolation of the once proud city took place, not immediately, but hundreds of years later. By the first century B.C., it had become a desert. Therefore, if the critics must find a post-exilic author for the first part of this prophecy, they must also find a post-60 B.C. for the author of Isaiah 13:20, below.! It is really surprising that they have not invented such an author. Nothing is too absurd for Bible enemies.
