Daniel 3:16

The three young men told the king that they did not need to give him an answer. "We" is emphatic in the original text and implies a contrast with Yahweh. God would give the king an answer. Perhaps they meant that Nebuchadnezzar should have had no question about their loyalty to him. They did not need to argue that. Surely the king knew that their faith prohibited them from worshiping any god but Yahweh. They were known to be Jews (Daniel 1:6-7).
