At the end of the ten days the result was found to be quite the opposite of Melzar's expectations. Not only in personal appearance, but in physical activity and mental vigor, those who had been temperate in their habits exhibited a marked superiority over their companions who had indulged appetite.

The Lord regarded with approval the firmness and self-denial of these Hebrew youth, and His blessing attended them. He “gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams” (Daniel 1:17). At the expiration of the three years of training, when their ability and acquirements were tested by the king, he “found none like Daniel, Hananiah, Mishael, and Azariah: therefore stood they before the king. And in all matters of wisdom and understanding, that the king enquired of them, he found them ten times better than all the magicians and astrologers that were in all his realm” (verse 20).SL 22.3
