Of particular interest to biblical scholars are Chapters 44–50, in which Ben Sira praises “men of renown, and our fathers in their generation”, starting from the antediluvian Enoch and continuing through to “Simon, the high priest, son of Onias” (300–270 BCE). Within this recitation, Ben Sira identifies, either directly or indirectly, each of the books of the Old Testament that would eventually become canonical, with the apparent exception of only Ezra, Daniel, Ruth, Esther, and perhaps Chronicles. The ability to date the composition of Sirach within a few years given the autobiographical hints of Ben Sira and his grandson (author of the introduction to the work) provides great insight regarding the historical development and evolution of the Jewish canon.
