Daniel 1:17-21

God gave these four young men knowledge and understanding in every kind of literature and wisdom. Daniel also understood visions and dreams of every kind. At the end of the time that the king had said to present them, the chief eunuch presented them to Nebuchadnezzar. The king interviewed them, and among all of them, no one was found equal to Daniel, Hananiah, Mishael, and Azariah. So they began to attend the king. In every matter of wisdom and understanding that the king consulted them about, he found them ten times better than all the magicians and mediums in his entire kingdom. Daniel remained there until the first year of King Cyrus.
