Jeremiah 10:5: The passage explicitly calls the object an idol, not a tree

Verse 5 calls these objects 'idols' — shaped images covered with silver or gold that people worship. God then mocks the idols by comparing them to scarecrows in a cucumber field: they can't speak, can't move, can't do anything. The crow-and-scarecrow analogy is God mocking pagans who worship dead objects: just as birds are fooled by a motionless scarecrow into thinking it's a real person, pagans are fooled by their idols into thinking a dead object has divine power.
