The queen tells Belshazzar about Daniel
5:10This queen was probably Belshazzar's mother, or Nabonidus's wife. She knew things about Daniel that the king did not know.
10 The king's mother heard the voices of the king and his officers. So she came into the room where they were having the party. She said to the king, ‘King, live for ever! Do not be afraid. Do not shake with fear! 11 There is a man in your kingdom who has the spirit of the holy gods in him. When your father was alive, this man showed that he was very wise, like the gods. He could understand secret things. Your father, Nebuchadnezzar, made him the leader of all the magicians, wise men, enchanters and diviners. 12 His name was Daniel, but the king called him Belteshazzar. He was very clever and he knew many things. He could explain what dreams mean. He could find the answer to difficult problems. Send somebody to bring Daniel here. He will tell you what these words mean.’
