Serious Question for Translational Perfectionist

Often there is not as much difference as it may first appear in English. I think mostly what we are witnessing is the difference between the MT and the LXX. However, there are also some rare ancient language words that are difficult to define. In addition, there are some subjective choices made in English even when Hebrew and Greek words with similar meanings are rendered. The KJV translators perhaps could have justified further the synchronizing of the words in these two passages.
The KJV translation of Isaiah 61:1,2a is displayed line-by-line above Luke 4:18,19 (and Brenton's 1851 English LXX beneath them) --

Where text is parallel (OT and NT), the wording is virtually the same in the original languages. Unsupported text in the NT caused the major difference. Could this have just been the NT author's parenthetical thought inserted?

 

FTR, I do agree that there is little significant difference in meaning.

However, the answer to your question is that "No! This was not a paranthetical comment inserted.", for the text tells us that Jesus stood up to read, and apparently did read this, and followed it up with His own words that the Scripture was fullfilled, at that time.

But if the Bible is inspired by God (and here I have in mind direct inspiration, automon like), then why aren't these quotes exact and why can't we find from where the author (God!) is quoting?

 

Simply because God is not a man.
