Daniel 2:17

Then Daniel went to his house -It is quite evident that he had obtained the object of his request, though this is not expressly mentioned. The king was undoubtedly, for the reasons above stated, willing that he should have a fair opportunity to try his skill in disclosing the mysterious secret. And made the thing known to Hananiah ... -Made the whole matter known - the perplexity respecting the dream; the failure of the Chaldeans to interpret it; the decree; and his own petition to the king. They had a common interest in knowing it, as their lives were all endangered.
