The queen was concerned (Dan 5:10-5:10)

“When the queen heard

The discussion

Of the king

With his lords,

She came into

The banquet hall.

The queen said.

‘O king!

Live forever!

Do not let your thoughts

Terrify you!

Do not let your face

Grow pale!’”

The queen or the queen mother heard the things and the discussions happening in the banquet hall. Thus, she came in and gave the usual greeting to the king. She told him not to be terrified or pale. Just take it easy and relax! If she was the queen, she would have been at this party, but she might have been the mother of Belshazzar or the queen mother.
