Sit thou silent,.... Here the speech is directed again to Babylon, which used to be a place of noise and hurry, as well as famous and much talked of all the world over; but now there should be a deep silence in it, no voice to be heard, the inhabitants being gone, and no discourse concerning it; no more talked of and celebrated for its magnificence and authority, trade and riches, but buried in oblivion.
It is represented as sitting in silence, either as a mourner, or as one that is free among the dead, remembered no more:and get thee into darkness, O daughter of the Chaldeans; meaning either captivity or imprisonment, prison houses being dark; or into the state of the dead, which is a state of darkness:for thou shall no more be called the lady of kingdoms; the mistress or governess of them, as she had been, having subdued many kingdoms and nations, and added them to her monarchy, which now would be at an end.
