The rebuilding of the walls around Jerusalem following the Babylonian exile was vitally important for several reasons according to the Bible.
Protection from Enemies
One of the main reasons it was important to rebuild the walls was for protection. Jerusalem had been left vulnerable after the Babylonian destruction. Walls provided security against potential attacks. Nehemiah recognized this need for safety when he inspected the damage and rallied the people to rebuild, saying “You see the trouble we are in: Jerusalem lies in ruins, and its gates have been burned with fire. Come, let us rebuild the wall of Jerusalem, and we will no longer be in disgrace” (Nehemiah 2:17). Thick, high walls deterred invading armies and kept the people safe from harm.
Preserve the City
In addition to protection, the walls helped preserve and maintain the city itself. After surviving exile in Babylon, the returnees wanted to reestablish their community and rebuild the ruins. Constructing the walls provided stability and a defined border. Nehemiah knew restoring the physical boundaries around Jerusalem was necessary to make it a functioning city again, rather than just a rubble heap. The walls gave shape and structure to the urban center, which was critical for daily life and operations to resume.
Unify the People
Furthermore, working together to rebuild the walls unified the Jewish exiles. The construction project required a collaborative effort from people across Jerusalem. Nehemiah organized different groups to work on various sections – priests, goldsmiths, officials, merchants, etc. As they labored side by side, they shared a common purpose and goal. The walls bound them together as they bonded over the grunt work. Unity gave them strength and energized the rebuilding process. When enemies like Sanballat tried to intimidate the workers, Nehemiah declared: “The God of heaven will give us success. We his servants will start rebuilding…” (Nehemiah 2:20). Their teamwork and community allowed them to persevere.
Fulfill God’s Plans
In addition, rebuilding the walls enabled the returnees to fulfill God’s plans. By restoring Jerusalem’s walls, they took steps to make the city functional again where God could be worshipped and glorified. Walls rebuilt meant the temple could be rebuilt. Throughout the construction, they had to trust in God’s protection and provision. As Nehemiah told them: “Don’t be afraid of them. Remember the Lord, who is great and awesome…” (Nehemiah 4:14). Rebuilding the walls was part of God’s purpose for His people after the exile. It prepared Jerusalem and the temple for God’s intended purposes.
Repentance and Restoration
Moreover, the rebuilding project represented repentance and restoration for the Jewish nation. When Jerusalem’s walls were first destroyed, it came as judgment for the people’s rampant sin. Reconstructing the walls decades later symbolized a spiritual rebuilding as well. It signified that the people desired to turn from sin and return to righteous living. They wanted to rededicate their lives and city to the Lord. By taking the massive effort to rebuild the walls, they visibly consecrated themselves afresh to God’s purposes. It was a step toward national and spiritual renewal.
Withstand Future Exile
In the same vein, solid walls helped ensure the people would not go into exile again. A primary cause of the Babylonian exile was Jerusalem falling due to weak walls that could not withstand attack. Rebuilding solid, durable walls made the city defensible against foreign invasion. Sturdy fortifications prevented another deportation and protected the people from repeating that national disaster. Thick walls provided the line of defense necessary to avoid leaving the land God gave them. Secure walls kept them in the land of promise.
Confirm God’s Promises
Finally, reconstructing the walls verified God’s faithfulness to His promises. Despite Israel’s disobedience leading to exile, God had promised to bring His people back to the land. By rebuilding the walls, they saw God’s word coming true. It was tangible evidence of His commitment to gathering the exiles and restoring the nation. As Nehemiah recounted, “You have performed your words, for you are righteous” (Nehemiah 9:8). Steadfast walls reminded the people of God’s steadfast love and faithfulness. The walls around them testified to His trustworthiness in fulfilling promises.
In summary, rebuilding Jerusalem’s walls was vitally important for protection, preserving the city, unifying the people in a shared purpose, enabling them to fulfill God’s plans, representing repentance and restoration, helping them withstand future exile, and confirming God’s promise to reestablish them in the land. Sturdy walls provided security, stability, and structure for the returned exiles. The reconstruction project renewed their spiritual devotion and national identity. Jerusalem’s walls were a critical part of God’s plan for Israel after the Babylonian captivity.
