Isa. 14:25; The One Volume Bible Commentary, Dummelow, p. 426
“It is difficult to determine whether Isaiah is prophesying about the destruction of Sennacherib’s Assyrian army in 701 B.C. or the defeat of the army of the nations led by King Gog in the last days. (Compare Isaiah 36-37 with Ezek. 38-39). In both cases, the Lord’s punishment is felt by the wicked nations of the earth.” (Victor Ludlow, Isaiah: Prophet, Seer, and Poet, p. 189)
