Click to go to the e-sword website
E-Sword is one of the best bible software's I have used and it has an added bonus of being free. Its has loads of Bibles and manuscripts to download mostly free.
It comes with a King James Version of The Bible and I recommend you download a KJV with Strong's Concordance and also the Revised Version (RV) This is an 1881 version, that seems to be the best version of The King James Bible we can get hold of today, also it's not printed any more and so is a rare version. I also recommend you download The KJV with The Apocrypha.
This tool is a must for all Bible scholars and it gives anyone the ability to understand the original languages and manuscripts.
E-Sword had Bibles to download in many different languages as well.
