The prophets predicted fearful judgments against the Ammonites because of their hostility to Israel (Zeph. 2:8; Jer. 49:1-6; Ezek. 25:1-5, 10; Amos 1:13-15).
The national idol worshipped by this people was Molech or Milcom, at whose altar they offered human sacrifices (1 Kings 11:5, 7). The high places built for this idol by Solomon, at the instigation of his Ammonitish wives, were not destroyed till the time of Josiah (2 Kings 23:13).
