Daniel 1:15-21

And at the end of ten days their countenances appeared fairer, and they were fatter in flesh, than all the youths that did eat of the king’s dainties. So the steward took away their dainties, and the wine that they should drink, and gave them pulse. Now as for these four youths, God gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams. And at the end of the days which the king had appointed for bringing them in, the prince of the eunuchs brought them in before Nebuchadnezzar. And the king communed with them; and among them all was found none like Daniel, Hananiah, Mishael, and Azariah: therefore stood they before the king. And in every matter of wisdom and understanding, concerning which the king inquired of them, he found them ten times better than all the magicians and enchanters that were in all his realm. And Daniel continued even unto the first year of king Cyrus.
