Jer 49:1-39. PREDICTIONS AS TO AMMON, IDUMEA, DAMASCUS, KEDAR, HAZOR, AND ELAM.

      The event of the prophecy as to Ammon preceded that as to Moab (see on Jer 49:3); and in Eze 21:26-28, the destruction of Ammon is subjoined to the deposition of Zedekiah.

      1. Hath Israel . . . no heir?--namely, to occupy the land of Gad, after it itself has been carried away captive by Shalmaneser. Ammon, like Moab, descended from Lot, lay north of Moab, from which it was separated by the river Arnon, and east of Reuben and Gad (Jos 13:24, 25) on the same side of Jordan. It seized on Gad when Israel was carried captive. Judah was by the right of kindred the heir, not Ammon; but Ammon joined with Nebuchadnezzar against Judah and Jerusalem (2Ki 24:2) and exulted over its fall (Ps 83:4-7, 8; Zep 2:8, 9). It had already, in the days of Jeroboam, in Israel's affliction, tried to "enlarge its border" (2Ki 14:26; Am 1:1, 13).
      their king-- (Am 1:15); referring to Melchom, their tutelary idol (Zep 1:5); and so the Septuagint reads it here as a proper name (1Ki 11:5, 33; 2Ki 23:13). The Ammonite god is said to do what they do, namely, occupy the Israelite land of Gad. To Jehovah, the theocratic "King" of Israel, the land belonged of right; so that their Molech or Melchom was a usurper-king.
      his people--the people of Melchom, "their king." Compare "people of Chemosh," Jer 48:46.
