This masculine noun form denotes incense, parallel to the more common feminine qetoreth. Malachi 1:11 uses it in a remarkable prophecy: 'In every place incense will be offered to my name, and a pure offering.' The verse envisions Gentile worship surpassing corrupt Jewish sacrifices. Some scholars debate whether this is a participial form ('what is burned') or a distinct noun, but the sense is clear: aromatic substances burned as worship. The word's rarity and morphological distinctiveness have led some translators to leave it untransliterated.
