isaiah 24:16 From the uttermost part of the earth have we heard songs, even glory to the righteous. But I said, My leanness, my leanness, woe unto me! the treacherous dealers have dealt treacherously; yea, the treacherous dealers have dealt very treacherously. - Free Bible Online

      16. Songs to God come in together to Palestine from distant lands, as a grand chorus.
      glory to the righteous--the burden of the songs (Isa 26:2, 7). Amidst exile, the loss of their temple, and all that is dear to man, their confidence in God is unshaken. These songs recall the joy of other times and draw from Jerusalem in her present calamities, the cry, "My leanness." HORSLEY translates, "glory to the Just One"; then My leanness expresses his sense of man's corruption, which led the Jews, "the treacherous dealers" (Jer 5:11), to crucify the Just One; and his deficiency of righteousness which made him need to be clothed with the righteousness of the Just One (Ps 106:15).
      treacherous dealers--the foreign nations that oppress Jerusalem, and overcome it by stratagem (so in Isa 21:2) [BARNES].
