Setting out in pursuit, the prophet follows the trail of the man of God from Judah. He eventually catches up to the traveler, finding him sitting and taking a rest from his journey [ביאור שטיינזלץ]. The man has chosen a spot under a specific type of tree [מצודת ציון], seeking comfort and shelter in its shade [רלב״ג].
Approaching the resting traveler, the prophet asks if he is indeed the man of God. The traveler gives a clear and direct confirmation of his identity, acknowledging that he is the very man being sought [ביאור שטיינזלץ].
