Daniel 1:17-21

As for these four youths, God gave them knowledge and intelligence in every branch of literature and wisdom; Daniel even understood all kinds of visions and dreams. Then at the end of the days which the king had specified for presenting them, the commander of the officials presented them before Nebuchadnezzar. The king talked with them, and out of them all not one was found like Daniel, Hananiah, Mishael and Azariah; so they entered the king’s personal service. As for every matter of wisdom and understanding about which the king consulted them, he found them ten times better than all the magicians and conjurers who were in all his realm. And Daniel continued until the first year of Cyrus the king.
