‘Then was Daniel brought in before the king. The king spoke and said to Daniel, “Are you that Daniel who is of the children of the captivity of Judah, whom the king my father brought out of Judah? I have heard of you that the spirit of the gods is in you, and that light and understanding and excellent wisdom is found in you. And now the wise men and enchanters have been brought in before me, that they might read this writing and make its interpretation known to me. But they could not show the interpretation of the thing. But I have heard of you, that you can give interpretations and resolve doubts. Now if you can read the writing, and make its interpretation known to me, you will be clothed with purple, and have a chain of old around your neck, and you shall be the third ruler in the kingdom.” '
Note the first description of Daniel. ‘Of the children of the Captivity of Judah'. This was the description seemingly used when the intention was to be polite (compare Daniel 2:25 and contrast Daniel 3:12). It explained their presence in the land and that they were there at the king's ‘invitation'. The use of his Hebrew name may have been because that was the name that Daniel asked to be announced, or it may be that that was the name by which he was referred to in the dossier probably handed to the king. That he had seen such a dossier is suggested by the fact that Belshazzar knew what he was.
Note also the continual emphasis on Daniel's qualities. All who read them knew that this was because God was with him. It was not glorifying Daniel but God, for God was the source of all his wisdom. And the same promise of high reward was given to him, if he could only solve the meaning of the writing.
On the other hand Belshazzar himself is revealed as at least neutral towards the gods. He omits the adjective holy. This fits in with his treatment of the holy vessels. He treated them with some disdain. He was more aware of his own status. The ‘I' in Daniel 5:16 is emphatic.
