From H5549 (salal, 'to lift up/cast up'). Solelah refers to the artificial earthen ramp or mound constructed by a besieging army against a city wall β the essential technology of ancient siege warfare.
The solelah appears in prophecies of judgment: Ezekiel declares that God Himself will cast up a solelah against Jerusalem (4:2); Jeremiah describes the Babylonians building siege mounds. This imagery makes a profound theological point β when God judges His people, He uses nations as His instruments of siege warfare. Yet the same God who allows the solelah to be built against the rebellious city also promises to build a solelah of grace β to level the ground of human pride, cast up the highway for the King's return (Isaiah 40:3β5). Every siege in history anticipates the final dismantling of every stronghold by the gospel (2 Cor. 10:4).
