Ісая 14:10

And how do they greet this lofty new-comer? "They all rise up and say to thee, Art thou also made weak like us? art thou become like us?" This is all that the shades say; what follows does not belong to them. The pual chullâh (only used here), "to be made sickly, or powerless," signifies to be transposed into the condition of the latter, viz., the Repahim (a word which also occurs in the Phoenician inscriptions, from רפא = רפה, to be relaxed or weary), since the life of the shades is only a shadow of life (cf., εἴδωλα ἄκικυς, and possibly also καμόντες in Homer, when used in the sense of those who are dying, exhausted and prostrate with weakness). And in Hades we could not expect anything more than this expression of extreme amazement. For why should they receive their new comrade with contempt or scorn? From Isa 14:11 onwards, the singers of the mashal take up the song again.

In this chapter, I. More weight is added to the burden of Babylon, enough to sink it like a mill-stone; I. It is Israel's cause that is to be pleaded in this quarrel with Babylon (Isa 14:1-3). 2. The king of Babylon, for the time being, shall be remarkably brought down and triumphed over (v. 4-20). 3. The whole race of the Babylonians shall be cut off and extirpated (Isa 14:21-23). II. A confirmation of the prophecy of the destruction of Babylon, which was a thing at a distance, is here given in the prophecy of the destruction of the Assyrian army that invaded the land, which happened not long after (Isa 14:24-27). III. The success of Hezekiah against the Philistines is here foretold, and the advantages which his people would gain thereby (Isa 14:28-32).

14:10 weak as we are: The Babylonian king had no power over anyone after death and was unable to leave Sheol. The Israelites will mock this great king who on earth appeared to have no weaknesses.
