'Upset' in the Bible

Then Daniel (whose name is also Belteshazzar) was upset for a brief time; his thoughts were alarming him. The king said, "Belteshazzar, don't let the dream and its interpretation alarm you." But Belteshazzar replied, "Sir, if only the dream were for your enemies and its interpretation applied to your adversaries!

When the king heard this, he was very upset and began thinking about how he might rescue Daniel. Until late afternoon he was struggling to find a way to rescue him.
