Concerning the Ammonites - This prophetic discourse was also delivered after the capture of Jerusalem.
Hath Israel no sons? - no heir? - The Ammonites, it appears, took advantage of the depressed state of Israel, and invaded their territories in the tribe of Gad, hoping to make them their own for ever. But the prophet intimates that God will preserve the descendants of Israel, and will bring them back to their forfeited inheritances.
Why then doth their king - מלכם Malcom or Milcom, the chief idol of the Ammonites. That the idol Milcom is here meant is sufficiently evident from Jeremiah 49:3, where it is said: "Milcom (not their king) shall go into captivity; his Priests and his princes together." Milcom is also called Molech. Malcom is put here for the Ammonites, as the people of Chemosh in the preceding chapter are put for the Moabites in general.
Hath Israel no sons? - i. e., the Ammonites in seizing Gilead have acted as if the country had no rightful owner. The sons of Israel were to return from captivity, and the land was their hereditary property.
Their king - Milcom (and in Jeremiah 49:3), see the margin. The Ammonite god stands for the Ammonites just as Chemosh Jeremiah 48:7 is the equivalent of the Moabites.
Inherit - i. e., take possession of.
