What does Isaiah 2:15 mean?
In the ancient world, the size, strength, and thickness of a city's towers and walls determined its ability to stand against attack and invasion. Those cities with the greatest walls and towers imagined themselves to be beyond the reach of any foe. Arrogance based on material power is a consistent theme in human history. Isaiah now adds these to the list of things the Lord will bring down when their day comes (Isaiah 2:13–18).On the day of the Lord (Ezekiel 30:3; Obadiah 1:15; Acts 2:20; 2 Peter 3:10), He will be exalted above towers, walls, and every other form of human defense (Revelation 6:15–17). Human structures, no matter how impressive, are no match for the power of the Lord (Psalm 20:7; Proverbs 11:28; Luke 12:16–21). He alone will stand undefeated in that time.
