The first bracha leading up to the Shema tells us that G-d forms light and creates darkness, which is based on this verse. Rashi explains this is not only in the sense of illumination, but also metaphysically. “I form light” – for the Jews in exile, when He made Cyrus king, leading to the restoration of the Temple - “and create darkness” – for the Babylonians, who had exiled the Jews for 70 years.
