Transitioning from a shocking Divine encounter to actually receiving a prophetic message requires profound intervention. Overwhelmed by the sheer power of the vision, the prophet loses his senses and collapses. In this weakened state, he needs both physical and mental reinforcement to absorb the upcoming message. A new, external spirit of awakening enters him at the exact moment a voice begins to speak. This spirit serves to rescue him from his collapse, taking hold of him and physically supporting him until he is back on his feet [מצודת דוד, רד״ק, ביאור שטיינזלץ].
Being lifted upright is not merely a physical restoration, but a necessary preparation for his mind. While lying on the ground in a state of shock, the prophet could only hear a muffled, incomprehensible sound. Once he is stood on his feet and his strength is restored, his mental clarity returns. This upright posture allows him to fully grasp the speaker's intent [מלבי״ם] and clearly hear the exact words being spoken [מצודת דוד].
The way the prophet hears this voice carries deep meaning regarding how God communicates. The language used to describe the speaker suggests a voice that is speaking to itself, rather than actively directing its words at someone. This subtle distinction is meant to preserve the honor of God, avoiding the impression of a casual, face-to-face conversation between two friends. Instead, it conveys that the Divine Presence is speaking out of Its own glory into the open space of the world. The prophet simply listens to the voice echoing in that space, absorbing the message without seeing its source or experiencing a direct, personal address [רש״י, ביאור שטיינזלץ].
