'Dismayed' in the Bible

“Then Daniel, whose [Babylonian] name was Belteshazzar, was appalled and speechless for a while [because he was deeply concerned about the destiny of the king], and his thoughts alarmed him. The king said, ‘Belteshazzar, do not let the dream or its interpretation frighten you.’ Belteshazzar answered, ‘My lord, may the dream be [meant] for those who hate you and its message for your enemies!

And I, Daniel, was overcome, and I became ill for [some] days, and I {performed} the business of the king, and I was dismayed over the vision and {I did not understand it}.
