When King James or Authorized Version of the Bible was published in 1611, it contained between the Old and New Testaments, the books of the Apocrypha. These are books and portions of books that appear in the Latin Vulgate, either as part of the Old Testament or as an appendix, but are not in the Hebrew Bible. With the exception of 2 Esdras, these books appear also in the Greek version of the Old Testament that is known as the Septuagint.
Books can be attributed to "Anonymous" for several reasons:
* They are officially published under that name * They are traditional stories not attributed to a specific author * They are religious texts not generally attributed to a specific author
Books whose authorship is merely uncertain should be attributed to Unknown.
Having read the complete Old and New Testaments last year, I decided to tackle the Apocryphal / Deuterocanonical Books of the Old Testament in 2025. While they focus on the Old Testament, it is easy to see why they were not included in the "standard" Bible Old Testament.
These books add additional history material about the Israelites, as well as reference the Flood, the release from captivity in Egypt, and various lesser prophets of Old Testament times. The books provide additional genealogies, talk about various battles fought by Israel, provide parallels to advice giving found in Psalms and Proverbs, and detail the times when Israel was faithful and unfaithful to God.
Having crossed this grouping of 18 books off my list to be read, I don't see a lot of value in ever reading them again.
