Large hailstones, specifically invoked in Ezekiel's prophecies of judgment. The term is a loanword from Arabic, related to gypsum or alabaster, perhaps reflecting the pale, stone-like appearance of hail. Ezekiel uses this imagery in oracles against false prophets and in the climactic battle against Gog, where hail joins fire, brimstone, and torrential rain as instruments of divine wrath. The image recalls the seventh plague in Egypt and other instances where God weaponizes weather to execute judgment.
