Listen to Bible (DRV) Apocrypha/Deuterocanon: Additions to Esther on your phone!
An additional six chapters appear interspersed in Esther in the Septuagint, the Greek translation, which then was noted by Jerome in compiling the Latin Vulgate; additionally, the Greek text contains many small changes in the meaning of the main text. The extra chapters include several prayers to God, perhaps because it was felt that the above-mentioned lack of mention of God was inappropriate in a holy book. Jerome recognized them as additions not present in the Hebrew Text and placed them at the end of his Latin translation as chapters 10:4-16:24. However, some modern Catholic English Bibles restore the Septuagint order, such as Esther in the NAB. (Summary by Wikipedia)
