The final moment of separation between a master prophet and his student marks the ultimate peak of transferring spiritual leadership. Witnessing the physical departure serves as a living testimony and the final seal of this new role. As the younger prophet watches his master ascend from the earth into the heavens [רד״ק, מצודת דוד], the sight is much more than a simple event. It serves as direct proof that a previously established condition has been met, confirming that the student is now fully worthy to inherit his master's spirit [מלבי״ם].
Overcome with emotion, the student cries out, calling his master his father. Commentators agree that this expresses deep respect and affection [ביאור שטיינזלץ], serving as a declaration of devotion to his teacher [רש״י, רד״ק, מצודת דוד]. A teacher is addressed as a father because he gives birth to a student's intellect and shapes his spirit, much like how students in the Bible are known as the sons of the prophets [רלב״ג, רד״ק]. The cry continues, comparing the departing prophet to the chariots and horsemen of Israel. The primary approach among commentators is that this highlights the master's immense power and his role as the nation's protector. His prayers defended Israel from its enemies far more effectively than any physical army of horses and chariots, making him the true strength and shield of the people [רש״י, רד״ק, מצודת דוד, רלב״ג, ביאור שטיינזלץ]. On the other hand, some explain this cry as a profound spiritual realization. The student understood that the fiery chariots were the divine vehicle through which God guides and watches over Israel, and that his master's greatness was equal to the entire nation [מלבי״ם].
The physical connection is finally broken as the chariot and horses of fire create a barrier between the two, separating them until the older prophet disappears from sight completely [רד״ק, מלבי״ם, ביאור שטיינזלץ]. The intense pain of this separation takes physical form when the new leader tears his garments into exactly two pieces [מצודת דוד]. From this action, the sages derived the religious law that requires a person to tear their clothes in mourning for a teacher who imparted wisdom to them [מלבי״ם, רד״ק]. The specific act of tearing the clothing into two pieces is not random. It reflects the sheer intensity of the grief, representing a deep, heavy sorrow that will never truly heal. Because of this, religious law dictates that this specific tear must never be sewn back together, remaining permanently visible as a lasting mark of loss [רד״ק, ביאור שטיינזלץ].
