Shakespeare was contemporary with the KJV. Do you think that Shakespeare needs to be translated, or do you think the English in his writings is perfectly understandable without explanation?
"The King James Bible was published in the year Shakespeare began work on his last play, The Tempest. Both the play and the Bible are masterpieces of English, but there is one crucial difference between them. Whereas Shakespeare ransacked the lexicon, the King James Bible employs a bare 8000 words—God’s teaching in homely English for everyman."
(Robert McCrum, William Cran, and Robert MacNeil, The Story of English, p. 113)"
