דניאל, פרק א׳, פסוק כ׳

The spiritual and intellectual brilliance of the young Jewish men in Babylon becomes undeniable when they stand trial before the highest officials of the empire. King Nebuchadnezzar was a man of broad knowledge, which equipped him to properly test and accurately measure their wisdom [אבן עזרא]. Whenever a situation required counsel, the king would gather all his wise men, only to consistently find that Daniel and his companions vastly outperformed the rest [מלבי״ם]. This massive gap in intellect was not merely a superficial impression born of casual conversation. It was objectively proven when the king challenged them with complex questions. The results of these practical tests made it clear that their superior minds were not the natural result of eating a diet of fine royal delicacies. Rather, their brilliance was a direct gift from God, granted to them as a reward for their dedication to keeping His Commandments and their refusal to defile themselves with the king's food and wine [אלשיך].

Their exceptional minds possessed a unique combination of two distinct intellectual powers. They mastered the knowledge acquired through formal study, while also demonstrating the profound ability to deduce new conclusions and independently understand complex concepts from what they had learned [מצודת דוד, יוסף אבן יחיא, ביאור שטיינזלץ]. When evaluating them, the king found the young men to be ten parts better than the others [מצודת ציון]. While some understand this measurement literally, meaning they were exactly ten times smarter, others suggest that the number ten simply serves as a general expression to describe a massive, immeasurable advantage [אבן עזרא, ביאור שטיינזלץ].

During these evaluations, the young men were measured against two distinct groups of Babylonian experts [אבן עזרא]. The precise identity of the first group is a matter of discussion. Some view them as figures of the occult, such as necromancers who consulted the dead [רש״י] or as priests and magicians [ביאור שטיינזלץ]. Conversely, another approach understands this group in scientific and philosophical terms, identifying them as scientists specializing in the natural world [מצודת ציון] or masters of theoretical intellect [יוסף אבן יחיא]. A parallel discussion exists regarding the second group. They are sometimes described as mystics, such as astrologers attempting to manipulate astrological decrees [רש״י] or sorcerers [ביאור שטיינזלץ]. However, the scientific perspective identifies them instead as medical doctors [מצודת ציון] or experts in practical, applied intellect [יוסף אבן יחיא].
