The English-language King James Version (KJV) of 1611 followed the lead of the Luther Bible in using an inter-testamental section labelled "Books called Apocrypha", or just "Apocrypha" at the running page header.
The Biblical apocrypha (from the Greek word aπόκρυφος, apókruphos, meaning "hidden") denotes the collection of ancient books found, in some editions of the Bible, in a separate section between the Old and New Testaments or as an appendix after the New Testament.
The King James Version (KJV), commonly known as the Authorized Version (AV) or King James Bible (KJB), is an English translation of the Christian Bible for the Church of England begun in 1604 and completed in 1611.
Despite being placed in the Apocrypha, in the table of lessons at the front of some printings of the King James Bible, these books are included under the Old Testament.
Although the term apocrypha had been in use since the 5th century, it was in Luther's Bible of 1534 that the Apocrypha was first published as a separate intertestamental section.
