Adam Clarke on Isaiah 29:5

The multitude of thy strangers "The multitude of the proud" - For זריך zarayich, thy strangers, read זדים zedim, the proud, according to the Septuagint; parallel to and synonymous with עריצים aritsim, the terrible, in the next line: the ר resh was at first ד daleth in a MS. See note on Isa 25:2.

The fifth, sixth, and seventh verses contain an admirable description of the destruction of Sennacherib's army, with a beautiful variety of the most expressive and sublime images: perhaps more adapted to show the greatness, the suddenness, and horror of the event, than the means and manner by which it was effected. Compare Isa 30:30-33.
