This verse paints a picture of a hopeful future where God's people, who have been scattered and oppressed, will be gathered together once more. The sounding of a great trumpet symbolizes a divine call, an invitation for those who have been living in distant lands, such as Assyria and Egypt, to return. These lands represent places of exile and hardship. The promise is that they will come back to worship the Lord on the holy mountain in Jerusalem, a place symbolizing God's presence and peace.
The imagery of the trumpet is significant in biblical literature, often associated with important announcements or divine interventions. Here, it signifies a moment of redemption and restoration, where the barriers of distance and separation are overcome. This gathering on the holy mountain is not just a physical return but also a spiritual renewal, emphasizing unity and the fulfillment of God's promises. It reassures believers of God's enduring faithfulness and the ultimate gathering of His people in a place of worship and community.
