I'm new here. I just read someone that crossreferences their bible with others i think that it's a great idea to do that.  I have nothing against the KJV but someone has pointed out that there have been older manuscripts then the ones used to make the kjv that have been discovered such as in the DSS.  To overlook this i think is just well one sided.

By the way i have 2 KJV that i know of. I might have one more somewhere.  

I think also to point out that there will be differences with the KJV and other modern Bibles. Since most modern Bibles use the DSS ands the KJV doesn't.  There are some that are just well  .  There is nothing wrong with the KJV or NASB. Just the different manuscripts that were used to translated it and that's no one's fault. Just used what was there.
