8 But Daniel resolved that he would not defile himself with the king’s rich food, or with the wine which he drank; therefore he asked the chief of the eunuchs to allow him not to defile himself. 9 And God gave Daniel favor and compassion in the sight of the chief of the eunuchs; 10 and the chief of the eunuchs said to Daniel, “I fear lest my lord the king, who appointed your food and your drink, should see that you were in poorer condition than the youths who are of your own age. So you would endanger my head with the king.” 11 Then Daniel said to the steward whom the chief of the eunuchs had appointed over Daniel, Hananiah, Misha-el, and Azariah; 12 “Test your servants for ten days; let us be given vegetables to eat and water to drink. 13 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.” 14 So he hearkened to them in this matter, and tested them for ten days. 15 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. 16 So the steward took away their rich food and the wine they were to drink, and gave them vegetables.

17 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. 18 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 Nebuchadnezzar. 19 And the king spoke with them, and among them all none was found like Daniel, Hananiah, Misha-el, and Azariah; therefore they stood before the king. 20 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.
