A noun meaning brightness, radiance, or shining light. It describes the luminous quality of something that shines — the brightness of the dawn, of divine glory, of lightning. It appears in prophetic visions of divine splendor and in descriptions of the morning light.
Nogah describes the quality of radiant light — not just that light exists but that it blazes with brilliance. It appears in Joel's description of the Day of the LORD as preceded by fire, in Habakkuk's vision of God's glory filling the earth, and in Ezekiel's complex vision of the divine chariot. The ultimate theological import is that God is surrounded by and constituted by blazing light — his holiness is not a moral category alone but a luminous reality that consumes impurity. Yet this brightness is also promise: the righteous will shine like the brightness of the firmament.
