Albert Barnes Commentary Jeremiah 48:7

"For, because thou hast trusted in thy works and in thy treasures, thou also shalt be taken: and Chemosh shall go forth into captivity, his priests and his princes together." — Jeremiah 48:7 (ASV)

Works - Possibly the products of labor. The versions render fortifications.

Chemosh - As the national god of Moab (Numbers 21:29), he represents the whole land; and his being led into captivity implies the total ruin of those under his protection. His name, here spelled Chemish, is repeated in Carchemish, that is, the fortress of Chemish.
