An idol is no better than a scarecrow. It can't speak, and it has to be carried, because it can't walk. Why worship an idol that can't help or harm you?
They chose their bull, then they got it ready and prayed to Baal all morning, asking him to start the fire. They danced around the altar and shouted, “Answer us, Baal!” But there was no answer.
This made the LORD very angry, and he sent a prophet to ask Amaziah, “Why would you worship these foreign gods that couldn't even save their own people from your attack?”
They carry the idol on their shoulders, then put it on a stand, but it cannot move. They call out to the idol when they are in trouble, but it doesn't answer, and it cannot help.
What can you learn from idols covered with silver or gold? They can't even breathe. Pity anyone who says to an idol of wood or stone, “Get up and do something!”
