5:10 Normally we would identify the queen as Belshazzar's wife. However, there are a number of reasons to prefer the view that she was really the queen mother or perhaps even the surviving wife of Nebuchadnezzar. Belshazzar's wives had been participating in this banquet (v. 2), but this woman now entered it apparently for the first time. She also spoke to the king more as a mother than as a wife.178Moreover she spoke as one who had personal acquaintance with Daniel's earlier interpretation of Nebuchadnezzar's second dream (cf. 4:8, 9, 18). Probably this woman was Belshazzar's mother and the daughter of Nebuchadnezzar.179The queen mother was often a significant figure who exerted considerable influence in ancient courts (cf. 1 Kings 15:13; 2 Kings 11:1-3; 24:12; Jer. 13:18). This woman proceeded to do for Belshazzar what Arioch had done for Nebuchadnezzar, namely, bring Daniel to the king's attention (cf. 2:25).
5:11-12 As before, Daniel had not accompanied the other wise men whom the king had summoned (cf. 4:6-8). The reason for this is unclear, but the effect in the event and in the narrative is that it sets Daniel off as unique. Clearly Belshazzar did not know Daniel personally. Perhaps Daniel had left public service.
When really severe crises arise, it is to the man or woman of God that others turn for answers.
