 One text does speak of official action at Jabneh.It gives a blanket statement that "all Holy Scripture defile the hands", and adds "on the day they made R. Eleazar b. Azariah head of the college, the Song of Songs and Koheleth (Ecclesiastes) both render the hands unclean" (M. Yadayim 3.5).Of the apocryphal books, only Ben Sira is mentioned by name in rabbinic sources and it continued to be circulated, copied and cited.
