The king had heard of Daniel by reputation even though he had not met him before (v. 13). He recognized him as a person whose extraordinary ability came from some divine source (cf. 4:8, 18). Perhaps it was because Daniel was a Jew that Belshazzar did not employ him in his administration. However now the king was quite willing to give even this Jewish exile all the honors that he had formerly promised his wise men. Here was a worshipper of the God that Belshazzar had been dishonoring in his banquet but who now might ironically prove superior to the Chaldeans. The king's willingness to reward a Jewish exile shows how desperately Belshazzar wanted to learn the meaning of the enigmatic message on the wall.
"As in the previous instances in Daniel 2 and 4, the wisdom of the world is demonstrated to be totally unable to solve its major problems and to understand either the present or the future. Daniel as the prophet of God is the channel through which divine revelation would come, and Belshazzar in his extremity was willing to listen.
"Too often the world, like Belshazzar, is not willing to seek the wisdom of God until its own bankruptcy becomes evident. Then help is sought too late, as in the case of Belshazzar, and the cumulative sin and unbelief which precipitated the crisis in the first place becomes the occasion of downfall."180
