Chemosh, was the god of the Moabites (Num. 21:29; Jer. 48:7, 13, 46). The word Chemosh meant the destroyer, subduer, or fish-god. Chemosh also means five in semitic languages. The term God (capitalized in English language as a proper noun) is often used to refer to a Supreme Being. ... Moab (מוֹאָב Seed of father/leader, Standard Hebrew Moʾav, Tiberian Hebrew Môʾāḇ) is the historical name for a mountainous strip of land in Jordan running along the eastern shore of the Dead Sea. ...
Chemosh was the national deity of the Moabites (Numbers 21:29; Jeremiah 47:7,13,46).
Little is known about Chemosh; although King Solomon of Israel built a sanctuary to him east of Jerusalem (1 Kings 11:7), the shrine was later abolished by King Josiah (2 Kings 23:13).
On the famous Moabite Stone, written by Mesha, a 9th-century-bc king of Moab, Chemosh received prominent mention as the deity who brought victory to the Moabites in their battle against the Israelites.
For Chemosh, "the abomination of Moab," as for Moloch, "the abomination of the children of Ammon," Solomon, under the influence of his idolatrous wives, built a high place in the mount before Jerusalem (1 Ki 11:7).
Chemosh is accordingly named because of his association with Moab, the cities of which are being spoken of, although strictly and literally Milcom should have been named in an appeal addressed as a whole to the Ammonites (Jdg 11:12-28; compare Moore at the place).
Mesha is himself the son of Chemosh, and it was for Chemosh that he built the high place upon which the monument was found.
