HELEL BEN SHACHAR = TWIN BROTHER OF SHALIM = HELEL SON OF SHAHAR

Lucifer
One of the most common misconceptions among Bible believers is that Lucifer is another name for Satan, based on a single occurrence of the word … the King James translation of Isaiah 14:12, which reads...

How art thou fallen from heaven, O Lucifer, son of the morning! How art thou cut down to the ground, which didst weaken the nations!

However the name "Lucifer" does not exist in the Hebrew text, nor the Greek translation (The Septuagint), but was derived from Jerome’s 4th century AD translation of this verse into Latin. Lucifer is a Latin name, which could not exist in a Hebrew manuscript, written before Latin even existed.

The KJV translators simply borrowed the name from Jerome's translation of the Bible. 

Note however that Jerome was not in error. Lucifer which means "light-bearer", was the fourth century Latin name for the planet Venus, which reaches its maximum brightness shortly before sunrise or shortly after sunset, for which reason it has been known as the Morning Star or Evening Star. As “Morning Star” Venus heralds daylight.

The Hebrew term translated in the KJV as “O Lucifer, son of the morning” is Helel ben Shahar.. literally ‘Helel son of Shahar’.  In the Babylonian / Canaanite religions, Helel which means to shine or to bear light, and Shalim, the god of dusk were twin brothers... sons of Shahar, the god of the dawn. Hence ‘Helel son of Shahar’
