John Calvin Commentary Isaiah 47:5

"Sit thou silent, and get thee into darkness, O daughter of the Chaldeans; for thou shalt no more be called The mistress of kingdoms." — Isaiah 47:5 (ASV)

Sit silent. He continues the same subject and shows that the end of the Babylonian monarchy is near. As this appeared to be incredible, he therefore repeats the same thing by a variety of expressions, and repeats what might have been said in a few words; and thus he brings forward those lively descriptions, in order to place the event, as it were, before their eyes.

When he bids her “sit” and be “silent,” it is an indication of shame or disgrace. Yet this silence may be contrasted with her former condition, while she reigned; for at that time not only did she speak loudly and authoritatively, but she cried with a loud voice, and by her commands terrified the whole of the East.

But now, in consequence of the change of her condition, he bids her “sit silent;” because not only will she not venture to utter terrifying words, but she will not even venture to make a gentle sound. But, since he adds, enter into darkness, I willingly adopt the former view, that it denotes shame; for those whose condition has been changed for the worse shut their mouth through shame and scarcely venture to whisper.

For it shall no longer be. We know that the Babylonian monarchy was very widely extended and exercised dominion over large and numerous countries, for it was the chief of many kingdoms. On this account, the captive people needed to be fortified by these promises and to be forewarned of her fall, that they might entertain assured hope of deliverance.
