Why would God dry up a sea and a river? It's more than just clearing a path; it's about demonstrating His overwhelming power to rescue and restore.
Isaiah 11:15 uses vivid imagery to paint a picture of God's mighty intervention. The "tongue of the Egyptian sea" likely refers to a bay of the Red Sea, and the "river" could be the Nile or the Euphrates. The imagery of drying up these bodies of water and striking the river into seven streams is a powerful echo of the Exodus, when God miraculously parted the Red Sea for His people.
This isn't just about geographical obstacles. It's a metaphor for God's ability to remove any barrier—political, spiritual, or personal—that stands in the way of His people's restoration and journey toward Him. The "scorching breath" and "mighty wind" emphasize the supernatural force at play, ensuring a safe passage "dry-shod" (in sandals, meaning without getting feet wet).
This signifies that when God decides to act on behalf of His people, no obstacle is too great. He doesn't just clear the path; He transforms the landscape itself to ensure their safe return and flourishing.
