In that day shall this song be sung in the land of Judah; We have a strong city; salvation will God appoint for walls and bulwarks. This verse opens Isaiah's great Song of Salvation, looking forward to the eschatological day when God's redeemed people celebrate His deliverance. The phrase "In that day" (בַּיּוֹם הַהוּא/bayyom hahu) is Isaiah's signature eschatological marker, appearing over 40 times in the book, pointing to God's final day of judgment and redemption when all His purposes reach fulfillment.
"We have a strong city" (עִיר עָז לָנוּ/ir oz lanu) contrasts sharply with Babylon's fallen strongholds mentioned in the preceding chapter. The Hebrew oz (strength, might, fortress) emphasizes impregnable security—not from human fortifications but from divine protection. Unlike earthly cities with stone walls that crumble, this city's strength derives from God Himself. "Salvation will God appoint for walls and bulwarks" (יְשׁוּעָה יָשִׁית חֹמוֹת וָחֵל/yeshuah yashit chomot vachel)—the Hebrew yeshuah (salvation, deliverance, victory) becomes the city's literal fortification. God doesn't merely defend the walls; salvation is the walls. The verb yashit (to set, establish, appoint) indicates deliberate divine action, while chomot vachel (walls and ramparts) were the double defensive system of ancient cities—outer and inner walls with a protective buffer between them.
Historical Context
Isaiah prophesied during 740-700 BCE, when Judah faced constant military threats from Assyria and other powers. Ancient Near Eastern cities depended entirely on their fortification walls for survival—a breached wall meant destruction, slavery, and death. Against this backdrop, Isaiah's vision of a city where salvation itself forms the walls would have been revolutionary. This contrasts with King Hezekiah's frantic wall-building projects in Jerusalem (2 Chronicles 32:5) when facing Assyrian invasion. The song looks forward to the New Jerusalem described in Revelation 21-22, where God's presence provides all security.
Questions for Reflection
How does trusting in God's salvation as your 'wall' differ from depending on human securities (finances, reputation, abilities)?
What does it mean that salvation is not just inside the city but IS the city's very defense?
How does this vision of the future city shape your response to present insecurities and threats?
