he Book of Sirach (/ˈsaɪræk/)[a] or Ecclesiasticus (/ɪˌkliːziˈæstɪkəs/; abbreviated Ecclus.)[3] is a Jewish work, originally written in Hebrew. It consists of ethical teachings, from approximately 200 to 175 BCE, written by the Judahite scribe Ben Sira of Jerusalem, on the inspiration of his father Joshua son of Sirach. Joshua is sometimes called Jesus son of Sirach or Yeshua ben Eliezer ben Sira. In Egypt, it was translated into Greek by the author's unnamed grandson, who added a prologue. This prologue is generally considered the earliest witness to a canon of the books of the prophets, and thus the date of the text is the subject of intense scrutiny. The book itself is the largest wisdom book from antiquity to have survived.[4]
