Daniel 1:19

So the steward took away their delicacies and the wine that they were given to drink, and gave them vegetables.

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.

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.

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 who were in all his realm.

Daniel continued even to the first year of King Cyrus.
