Faced with the prophet Elijah's request to summon King Ahab, Obadiah reacts with deep anxiety for his own life, viewing the mission as a literal death sentence. He cries out in distress, questioning what crime he could have possibly committed to justify being killed by the king [ביאור שטיינזלץ]. Obadiah directly accuses Elijah, arguing that by making this demand, the prophet is becoming the direct cause of his impending execution [מצודת דוד].
The root of this intense fear becomes clear as Obadiah explains the scenario he anticipates. He is terrified that the moment he leaves to call the king, the spirit of God will carry Elijah away to an unknown location. Consequently, when Ahab arrives and fails to find the prophet, the king will unleash his full rage on Obadiah and put him to death [רש״י].
