Which Greek? Do you own a complete copy of Greek Bible? Could you show me where is that completely called Greek Bible? All I know is that the scriptures were written in original languages of Hebrew, Koine Greek and Aramaic, then translated to other languages like Old Latin, Italic Version, French, Diodati, German then in English which the world knows it's a International languages so that we can interact with each other. Using your Greek and using my language will confuse everything. For me it's fine to learn Greek language but a never substitute for the pure words of God in English-KJV.
Greek Old testament is called LXX, it was used by the first church and is quoted in New testament.
I dont understand why it would confuse your language and why the original cannot be substitute for its translations...
But whatever, read what you want, but no translation can be the authority on the original text meaning.
