Actually Sarah, it is not. My Search Software is very precise. morning star (singular) only appears twice in the Authorized Version. And morning stars (plural) appears once.
I was talking about morning star (singular) because that is what is being discussed here. The rendering of morning star. Not so much morning stars.
But Chosen by using the same logic that you using to say the NIV is saying Jesus is the one who fell (Which I don't believe) the KJV is saying that Jesus is just an angel. Because if Jesus is just one of the morning stars that makes Him just an angel. (Which of course in not true) That of course is picking and choosing the verses I want to prove the point.
