Then Daniel said to the steward whom the chief of the eunuchs had appointed over Daniel, Hanani'ah, Mish'a-el, and Azari'ah;
"Test your servants for ten days; let us be given vegetables to eat and water to drink.
Then let our appearance and the appearance of the youths who eat the king's rich food be observed by you, and according to what you see deal with your servants."
So he hearkened to them in this matter, and tested them for ten days.
At the end of ten days it was seen that they were better in appearance and fatter in flesh than all the youths who ate the king's rich food.
So the steward took away their rich food and the wine they were to drink, and gave them vegetables.
As for these four youths, God gave them learning and skill in all letters 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 Nebuchadnez'zar.
And the king spoke with them, and among them all none was found like Daniel, Hanani'ah, Mish'a-el, and Azari'ah; therefore they stood 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 kingdom.
And Daniel continued until the first year of King Cyrus.
