What does Lucifer mean in latin?

'Lucifer' comes from the Latin lucem ferre, which mean 'light-bearer', a name for the dawn appearance of the planet Venus.

In The Bible, this first appeared in Isaiah chapter 14, a passage that refers to the king of Babylon, who laid the nations low. Isaiah talks of the king's pomp and splendour, how he had ruled the nations in anger, and his fate after his overthrow by the king of Persia. He had compared himself to the Morning Star and was thus derisorily called Lucifer. The king had thought that he would ascend into heaven and sit among the stars, but was now himself persecuted. This text was misunderstood by early Christian scholars and even some Jewish scholars of the period, with both assuming that it referred to Satan being cast down from heaven.
