The descendants of Ammon, or Ben-Ammi, a son of Lot. They destroyed an ancient race of giants called Zamzummim, and seized their country, which lay east of Judea, Deuteronomy 2:19-21. Their territory extended from the Arnon to the Jabbok, and from the Jordan a considerable distance into Arabia. Their capital city was Rabbah, (also called Rabbath Ammon, and afterwards Philadelphia,) which stood on the Jabbok. Yet in the time of Moses they had been driven out of this region, towards the east, by the Amorites, Numbers 21:21-35 32:33. Moses was forbidden to assail them, Deuteronomy 2:19. They were gross idolaters; their chief idol being Moloch, supposed to be the same with Saturn, 1 Kings 11:5-7 2 Kings 23:13. They oppressed Israel in the time of Jephthah, and were defeated by him with great slaughter, Judges 11:1-40. The children of Ammon afterwards, at various times, troubled the Israelites, for which the prophets threatened them with divine judgments, Jeremiah 46:1-6 Ezekiel 25:2-10.
