will break down every high tower and every fortified wall. He will
destroy all the great trading ships and every magnificent vessel. Human
pride will be humbled, and human arrogance will be brought down. Only
the LORD will be exalted on that day of judgment.
Isaiah 2:15-17, NLT
Lofty towers were part of a city or nation's defenses. This phrase refers to security based on military fortresses. "Great trading ships" pictures economic prosperity; and a "every magnificent vessel" reveals pleasure and enjoyment.
Nothing can compare with or rival the place God must have in our hearts and minds. To place our hope elsewhere is nothing but false pride. Place your confidence in God alone.
