If any of these agree with the KJV or any current English Bible, that means you are reading Septuagint as Scriputre and not the Hebrew Bible.

Is there any way to know that for certain? How do we know that many or most of these were not taken from the New Testament and just inserted into the Septuagint during the New Testament period, or during some of the revisions of the Septuagint, rather than vice versa???

Are the readings here from the Septuagint of Codex B, or Sinaiticus, or Alexandrinus or some later revisions? Hasn't the Septuagint been under revision for 2000 years and no one is really sure just what the pre-Origen Septuagint really was???

Does your Bible say in Matt 1:23 that a "young woman" or a "virgin" will give birth? If it's the latter, you're reading the Septuagint. If you wish to believe it was "inserted" that's your choice but your argument is weak. Isaiah is, I believe, one of those books of the LXX that was found that is actually older than Christianity and the word it has is "virgin" — parqenoV.
