“For, because you trusted in your works and your treasures, you also shall be taken; and Chemosh shall go into exile with his priests and his officials. The destroyer shall come upon every city, and no city shall escape; the valley shall perish, and the plain shall be destroyed, as the Lord has spoken.” (Jeremiah 48:7-8)

These verses refer to Moab. Chemosh is the idol of the Moabites. Here, God says Chemosh will be put down, and defeat shall fall upon all of Moab. The reason?  “Because you trusted in your works and your treasures.” (7)

Contrast that with Ruth who was from Moab and chose to follow the one true and living God: “But Ruth said, ‘Do not urge me to leave you or to return from following you. For where you go I will go, and where you lodge I will lodge. Your people shall be my people, and your God my God.’” (‭‭Ruth‬ ‭1‬:‭16‬)

There is a cost for trusting in ourselves. There is a benefit of trusting in the Lord.
