@tyler Summarizing this thing I just read, they pulled a lot of early Greek translations for the NT. I don't see the source on the OT. Seems to be the ye olde "best of" translation attempt, which would be good for the fact that it has strong resistance to modernism if nothing else. I'm sure there's more to it.
