Those manuscripts are unique, because, despite the fact that they have been written in the Hebrew alphabet, the language they have been written in is Persian. This is because the manuscript has been written by Mountain Jews (Tats), whose literary language until the 19th century was Persian.
Lo extraordinario de los manuscritos se basa en que, a pesar de que están escritos en el alfabeto hebreo, el idioma de la obra-es el idioma persa. Es porque el manuscrito fue escrito por los judíos de la Montaña (Tats), cuya lengua literaria hasta el siglo XIX era el idioma persa.
