Which agrees most with the Authorized version of the bible? Personally i’d say the Old Latin or the Vetus Latina. First off, the Vetus Latina contains scriptures usually left out by the Peshitta and confirms many New Testament scriptures.
The Vetus Latina is also what most people claim the Waldenses were protecting and that later turned into the first French Olivetan bible which also turned into the Geneva Bible. So we can easily say that the KJV or Geneva Bible had their roots in the Vetus Latina and not so much the Peshitta. I’m not saying the Peshitta is useless or anything but i’d stick with the Vetus Latina for now.
