Rashi: The queen, who stands to the king's right - "Nitzevah Shegal li'Yminecha" (Tehilim 45:10), she was openly exiled and raised from the city.

Radak citing his father: The palace, which stood in serenity many years, now it is melted and revealed. It was covered until now - no stranger passed through. Ho'alasah means 'was cut off', like 'ka'Alos Gadish b'Ito" (Iyov 5:26).

Radak citing R. Shmuel ha'Nagid: The queen's name was Hutzav. Normally, she was hidden in her room, like the conduct of a queen or honored woman - "Kol Kevudah Vas Melech Penimah" (Tehilim 45:14). Now she was revealed and left her room and ascended on the chariot to take her to Galus.

Malbim: The fire was prepared to burn the queen and concubines. Gulesah is the queen. She was put on the fire covered in a Tzav (chair used to carry officers).

Radak citing his father: The great female officers; they will be exiled like slaves.

Rashi: They show their feelings with lamentation, like the voice of doves.

Radak: They console her.

Rashi citing Targum Yonasan: They knock their hands over their hearts, like one who bangs a drum or tambourine. Radak - this is custom of women who lament. Radak citing his father - this is amidst pain over their lost honor, and going to exile like slaves.
