The NIV Bible is riddled with errors and in my opinion, some of them are deliberate. Let’s document that.
One example brings us to Isaiah 14:12.
KJV – “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!” – Isaiah 14:12
NIV – “How you have fallen from heaven, morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations!” – Isaiah 14:12
Notice, in the KJV Bible it is very specific with whom we are talking about, “Lucifer”. Satan and Christ are both known as the "Morning Star" so why remove the word “Lucifer” when it makes it abundantly clear who we are discussing?
Let us look at one more example. This time we are going to look at Ezekiel 13:16-20.
In the KJV, God says He is against those daughters who are false prophets, who teach the people to fly to save their souls.
In the NIV, this has been changed to capturing birds. A tremendous difference that alters the meaning of the topic at hand (I encourage the reader to cover the entire chapter to get the context).
