New Defender's Study Bible Notes
49:35 Elam. Elam was one of the most ancient nations, originally established by a son of Shem (Genesis 10:22). At the time of Jeremiah, in spite of its long and eminent history, it had been subjugated by the Assyrians and then the Babylonians. Eventually, however, with its capital Susa (or Shushan), it would become the key section of what would expand into the great empire of Persia. Then the combined empire of Media and Persia would finally conquer Babylon itself.
