Or is the Hebrew Bible's primary noun for light in all its physical and metaphorical richness. God's first creative word calls it into existence — 'Let there be light' (Gen 1:3) — and from that moment the word radiates through Scripture as both concrete phenomenon and profound symbol. Physically, it denotes daylight (Gen 1:4-5), morning dawn (Judg 16:2; 1 Sam 14:36), and the light of heavenly bodies (Isa 30:26). Metaphorically, its range is extraordinary: light as life itself (Job 3:20; Ps 56:13), as divine favor and salvation ('The LORD is my light,' Ps 27:1), as torah and moral guidance (Prov 6:23; Isa 2:5), and as eschatological glory (Isa 60:1, 19-20). Spanish luz and French lumiere both carry a similar physical-to-metaphorical range, while German Licht has the same dual register. The Arabic cognate nur (نور) became a divine attribute in Islam (Quran 24:35), showing how the Semitic light-word gravitates toward theological depth. A distinct sense appears in Job's storm poetry (36:30; 37:3, 11), where or denotes lightning — sudden, terrifying brilliance rather than steady illumination.
