The poem lauding the ancestors from Chapters 44 to 50 of Ben Sira (Ecclesiasticus) is considered by many scholars to be the original influence for the Yom Kippur Avodah service, and the paean to Shimon the Righteous bears a striking similarity to the beloved piyyut “Mar’eh Khohen.” This passage from Ben Sira, the great paean on the merit of the ancestors, takes the Hebrew text of one of the Cairo Geniza manuscripts — Bodleian MS Heb e62 — and versifies it according to the standard Septuagintal text, along with vocalization and cantillation per the standard Masoretic EMe”T system for poetic books. It could be read on Yom Kippur for the avodah service, or just studied as a fascinating piece of Jewish history. . . .
