When a person stands firm on spiritual principles against all odds, Divine Providence intervenes to clear the path. Daniel finds himself in a foreign court facing an impossible dilemma: refusing the daily food rations mandated by the most powerful ruler in the world. Naturally, making such a request is an act of rebellion that should carry an immediate death sentence. Instead, a miraculous shift occurs in the attitude of his captors.
The chief officer appointed over the king's servants [רש״י] had no reason to entertain this request. He was responsible for many youths and completely lacked the authority to grant anyone a special menu [ביאור שטיינזלץ]. In fact, this was the very same official who had just assigned pagan names to Daniel and his friends in an effort to assimilate them into Babylonian culture [אלשיך]. Yet, God intervened on Daniel's behalf, transforming even the harsh attribute of heavenly justice into mercy due to his merit [חומת אנך].
The primary approach among commentators is that the officer did not officially or immediately grant the request, as he feared for his own life from the king. Therefore, the divine kindness and mercy manifested in the officer's surprising reaction. Rather than scolding Daniel or punishing him for his dangerous audacity, the officer overlooked his boldness. He spoke gently to Daniel and felt true pity upon seeing the religious distress he was experiencing [מצודת דוד, אבן עזרא, מלבי״ם]. The greatest act of kindness was that the officer chose not to report Daniel's secret to the king—a revelation that would have cost Daniel his life. Furthermore, he later turned a blind eye when a lower-ranking guard actually altered the youths' diet [מצודת דוד, אבן עזרא, חומת אנך].
This divine intervention did not occur in a vacuum. Because Daniel had first made a firm, internal commitment to maintain his devotion to God regardless of the danger, God acted to grant him favor in the eyes of his captors [אלשיך]. Alongside his deep trust in God, Daniel also employed clever tactics. He initially made the request only for himself, leaving his friends out of the plea. Much like a poor man who asks for a small favor before making a larger request, Daniel understood that asking for a special diet for the entire group all at once would overwhelm the officer and harden his heart. By limiting the initial request to himself, Daniel successfully paved the way to secure the same arrangement for his friends later [אלשיך].
