Ammonite

the usual name of the descendants of Ammon, the son of Lot (Gen.
19:38). From the very beginning (Deut. 2:16-20) of their history
till they are lost sight of (Judg. 5:2), this tribe is closely
associated with the Moabites (Judg. 10:11; 2 Chr. 20:1; Zeph.
2:8). Both of these tribes hired Balaam to curse Israel (Deut.
23:4). The Ammonites were probably more of a predatory tribe,
moving from place to place, while the Moabites were more
settled. They inhabited the country east of the Jordan and north
of Moab and the Dead Sea, from which they had expelled the
Zamzummims or Zuzims (Deut. 2:20; Gen. 14:5). They are known as
the Beni-ammi (Gen. 19:38), Ammi or Ammon being worshipped as
their chief god. They were of Semitic origin, and closely
related to the Hebrews in blood and language. They showed no
kindness to the Israelites when passing through their territory,
and therefore they were prohibited from "entering the
congregation of the Lord to the tenth generation" (Deut. 23:3).
They afterwards became hostile to Israel (Judg. 3:13). Jephthah
waged war against them, and "took twenty cities with a very
great slaughter" (Judg. 11:33). They were again signally
defeated by Saul (1 Sam. 11:11). David also defeated them and
their allies the Syrians (2 Sam. 10:6-14), and took their chief
city, Rabbah, with much spoil (2 Sam. 10:14; 12:26-31). The
subsequent events of their history are noted in 2 Chr. 20:25;
26:8; Jer. 49:1; Ezek. 25:3, 6. One of Solomon's wives was
Naamah, an Ammonite. She was the mother of Rehoboam (1 Kings
14:31; 2 Chr. 12:13).

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).
