Overwhelmed by deep anxiety, Daniel undergoes a profound physical and mental awakening to prepare himself for prophecy. A speaker approaches him with words of comfort and peace, intending to dispel his intense fear so that his physical strength will not fail him [מצודת דוד]. This reassurance serves a vital purpose. On a personal level, it removes the immediate fear of death, promising Daniel physical health and restored bodily balance. On a broader level, it addresses a deep-seated worry regarding his people. He is assured that his nation will not be lost in this world or the next, as they are guaranteed hope and a lasting future [יוסף אבן יחיא].
To fully pull Daniel out of his fragile state, the speaker urges him with a repeated call for strength. This repetition serves to actively encourage him to gather his energy and fortify himself [מצודת דוד]. Furthermore, the dual nature of this command directly mirrors the two distinct fears he must let go of: the personal terror for his own life and the heavy, national anxiety for the fate of his people [יוסף אבן יחיא].
The encouragement achieves its goal. Daniel acknowledges his renewed vigor, confirming that the speaker's words successfully restored his spirit. Now, with his physical and mental energy fully recovered, he is finally ready, fit, and capable of listening to the prophetic message [מצודת דוד, ביאור שטיינזלץ].
