The book of Judith is included with the historical books of the Old Testament, but due to apparent historical inconsistencies, it might be more correct to understand it as a work of historical fiction. Nevertheless, Judith stands as an inspiring account of confident faith put into bold action.
The book of Judith is a tale of the beautiful and pious women Judith (which means Jewess) who daringly and single-handedly delivers the Jewish people from their enemies, using her beauty and charm, all the while remaining pure and chaste.
Judith is an Apocrypha book and not included in all versions of the Bible. The New Jerusalem Bible, Revised Standard Version (RSV), New American Bible (NABRE), Wycliffe Bible (WYC), Common English Bible (CEB), Good News Translation (GNT), and Douay-Rheims (DRA) all include Judith. Interestingly, the original Authorized King James Version (KJV) contains Judith, but the text was removed almost two centuries later. The Septuagint, an ancient Greek translation of the Jewish scriptures, which was widely used in Jesus’s day, also includes the book of Judith.
