Daniel 1:17-21

As for these four youths, God gave them learning and skill in all literature and wisdom, and Daniel had understanding in all visions and dreams. At the end of the time, when the king had commanded that they should be brought in, the chief of the eunuchs brought them in before Nebuchadnezzar. And the king spoke with them, and among all of them none was found like Daniel, Hananiah, Mishael, and Azariah. Therefore they stood before the king. And in every matter of wisdom and understanding about which the king inquired of them, he found them ten times better than all the magicians and enchanters that were in all his kingdom. And Daniel was there until the first year of King Cyrus.
