Isaiah 46:1

Ver. 1 Bel boweth down, Nebo stoopeth
These are names of theIsaiah 46:2

They stoop, they bow together
Either the beasts under their burdens, or other idols besides those mentioned; or rather the Babylonians themselves, who were obliged to submit to the conquerors: they could not deliver the burdens;
the idols could not save themselves from being laid as burdens upon the beasts, any more than they could save their worshippers: so the Targum understands this and the preceding clause of them;

``they are cut off, and cut to pieces together, they could not deliver those that carried them;''
or else the Babylonians are designed, who could not save their gods from being used in this shameful manner: but themselves are gone into captivity,
or "their souls" F13; what were as dear to them as their own souls, their idols; to whom also souls may be ascribed by way of derision, being inanimate as well as irrational; and it is not unusual for idols to be said to be carried captive; hence those words of Tertullian, "manent et simulachra caplira": or rather the Babylonians, who went into captivity themselves, and so could not save their idols: thus they who had led captive the Jews are led captive themselves; and thus it will be with mystical Babylon, ( Revelation 13:10 ) .
