Daniel 5:14
But I have heard that you can give interpretations and solve problems. Now if you can read the writing and tell me its interpretation, you shall be clothed in purple, and have a chain of gold around your neck, and rank third in the kingdom. Belshazzar dangles the same rewards promised to any successful interpreter: purple, gold chain, third rank. His assertion that he has heard Daniel can give interpretations expresses the hope that Daniel might succeed where others failed. The conditional framing (if you can) leaves room for doubt; the king is uncertain whether even Daniel can deliver. The repetition of the rewards indicates that they remain offered to whoever successfully interprets the writing.
