Read up on William Tyndale. He was fluent in 7 languages, Greek being one of them. Erasmus translated the Vulgate into Greek. Now, what Erasmus had were not mss(thanks bunches trof), but the Vulgate. Tyndale then took those texts of Erasmus' and translated them into English. Then later the KJV translators used Erasmus', Beza's, and Tyndale's(I think) to translate the word of God into the KJV.
abandon ship folks. its over.
i love the kjv still but i'll definately get that NASB now that i heard james white was in the translating commitee. its important to have saved folks translating it. the english is more modern too
