The prophet calls to men to publish it amongst other nations, and to set up a standard, to make some signal to gather all people together to hear what he had to say from God against Babylon, which had been an instrument of great mischief unto most people that lived about them, to whom it would therefore be glad and joyful news to hear that Babylon their common enemy was ruined. That by Bel and Merodach are meant two principal idols of the Babylonians, most think; but what, is not so well agreed. Some think that Bel is Baal by contradiction; but they judge most probably who think it was the image of one Belus, who was formerly a king of Babylon; and they judge the like of Merodach: we find in Scripture that Merodach was some of their kings names, Isaiah 39:1 Jeremiah 52:31. Those who desire to be further satisfied about these idols may read the English Annotations upon Isaiah 46:1, and our Annotations upon that verse. It was an ordinary practice amongst the heathens, when they had any princes died that had been famous in their government, to pay a divine homage to their images and statues. These idols are said to be confounded, either because they should not be able at this pinch to help their suppliants, or because they should be destroyed together with the silly people that adored them.
