Original sentence: Although Second Esdras was preserved in Latin as an appendix to the Vulgate and passed down as a unified book, it is actually a tripartite work
Edited sentence: According to this theory, the main body is a first-century Jewish apocalypse labeled "Fourth Ezra" (Chapters 3-14), which is bookended by two later Christian works known as "Fifth Ezra" (Chapters 1-2) and "Sixth Ezra" (Chapters 15-16).Although preserved in the 4th Century Latin Vulgate as a unified work and passed down in that form, most biblical scholars now believe it is actually of tripartite construction.It is believed to have been written in the late 1st century CE following the destruction of the Second Temple
