This noun refers to lime or whitewash, a white substance produced by burning limestone or bones. In Deuteronomy 27:2-4 the Israelites are commanded to set up large stones and coat them with lime before writing the law on them—creating a durable, visible white surface for the inscription. Amos 2:1 uses it in judgment against Moab for burning the bones of Edom's king 'to lime.' Isaiah 33:12 compares peoples to thorns cut down and burned to lime. The multilingual glosses (Spanish cal, French chaux, with some transliteration) confirm this as lime/plaster. The white coating serves both practical purposes (writing surface) and carries symbolic weight (purity, permanence, and in burning contexts, utter consumption).
