6:2 Daniel was first - Belshazzar's promise to Daniel was, that he should be the third ruler in the kingdom, chap.5:7,16,29. The first was general of the army, the second president of the palace, the third of the land and provinces.
6:1-5 We notice to the glory of God, that though Daniel was now very old, yet he was able for business, and had continued faithful to his religion. It is for the glory of God, when those who profess religion, conduct themselves so that their most watchful enemies may find no occasion for blaming them, save only in the matters of their God, in which they walk according to their consciences.
