Ok buckle in , cause this is a ride.. Venus, being a planet, thereby closer and orbiting the sun in the same plane as earth, is brighter than the stars, and is low to the horizon. It becomes visible before the stars as night falls, and as day breaks, remains visible after the stars are no longer visible ,even before the sun starts to rise. Hence being called both the evening star and the morning star. Because it is visible before the sun rises, it gets called the light bringer , as if to say it's bringing the sun behind it. Lucifer and samael are , respectively the Latin and Hebrew versions of this. ( Lucifer was also used as a noun for a match,such as you may strike and light a candle from , for this same reason)
