Isaiah 25:11-12 Amplified Bible (AMP)

11. And though [Moab] stretches forth his hands in the midst of [the filthy water] as a swimmer stretches out his hands to swim, the Lord will bring down [Moab's] pride in spite of the skillfulness of his hands and together with the spoils of his hands.

12. And the high fortifications of your walls [the Lord] will bring down, lay low, and bring to the ground, even to the dust.
