It wouldn’t be much of a study of GOD if you restricted yourself to one book, now would it. I use the KJV Bible, Tanach, Pentateuch and a barrage of software Bibles in English, Hebrew and Greek. I would like to give you a word of warning. Newly translated Bibles have been corrupted because we live in a time as to where man has lost the fear and respect of GOD. They have now started translating the Bible to make it be more in harmony with their own religious ideals and belief system, stick to the older translations, the older the better. And pay no attention to little titles and side notes man has placed in the text.
And it is true The Word of GOD doesn’t change, man does.
