Philip Comfort's book :Essential Guide To Bible Versions has been a very interesting read.(By the way,don't confuse him with Ray Comfort --The Way Of The Master).This book was published in the year 2000 by Tyndale House. There was something fasinating to me on page 172. "On the whole,the New American Standard Bible became respected as a good study Bible that accurately reflects the wording of the original languages.Yet it is not a good translation for Bible reading.Furthermore,it must be said that this translation is now nearly thirty years behind in terms of textual fidelity -- especially the New Testament,which,though it was originally supposed to follow the twenty-third edition of the Nestle text,tends to reflect the Textus Receptus... The NASB translators did not fully reflect the manuscript evidence of some very important discoveries in the decades prior to their work.The Dead Sea Scrolls were hardly influential in their work. And it seemed that they didn't take much notice of the Chester Beatty and Bodmer papyri for the New Testament."
