Charles Ellicott Commentary Judges 11:24

"Wilt not thou possess that which Chemosh thy god giveth thee to possess? So whomsoever Jehovah our God hath dispossessed from before us, them will we possess." — Judges 11:24 (ASV)

Chemosh your god. —The expression shows the close connection between Ammon and Moab. Chemosh was distinctively the god of Moab, and Moloch of Ammon; but the two nations were of kindred blood and allied institutions (Judges 3:12–13). The name Chemosh means “subduer,” and there is here, perhaps, a tacit reference to the wild popular song of triumph over the conquest of Heshbon, in which Chemosh is taunted by name (Numbers 21:29). The clause might be rendered, Whatever Jehovah our God has dispossessed before us, that we take in possession.
