The Book of Sirach or Ecclesiasticus 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.
