Adam Clarke on Isaiah 25:5

Of strangers "Of the proud" - The same mistake here as in Isa 25:2 (note): see the note there. Here זדים zedim, the proud, is parallel to עריצים aritsim, the formidable: as in Psa 54:5, and Psa 86:14.

The heat with the shadow of a cloud "As the heat by a thick cloud" - For חרב choreb, the Syriac, Chaldee, Vulgate, and two MSS. read כחרב kechoreb, which is a repetition of the beginning of the foregoing parallel line; and the verse taken out of the parallel form, and more fully expressed, would run thus: "As a thick cloud interposing tempers the heat of the sun on the burnt soil; so shalt thou, by the interposition of thy power, bring low and abate the tumult of the proud, and the triumph of the formidable."
