Where is the name Lucifer written in the Bible?

there is a reference to Lucifer in Isaiah chapter 14, but this refers to the king of Babylon, who laid the nations low. It talks of his 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' - lucem ferre, which mean "light-bearer", a name for the dawn appearance of the planet Venus) and had thought that he would ascend into heaven and sit among the stars, but was now himself persecuted. Christian scholars misunderstood this text and assumed that it referred to Satan or the devil.
