Exegesis (ˌɛksɪˈdʒiːsɪs ; from the Greek ἐξήγησις, from ἐξηγεῖσθαι, "to lead out") is a critical explanation or interpretation of a text. The term is traditionally applied to the interpretation of Biblical works. In modern usage, exegesis can involve critical interpretations of virtually any text, including not just religious texts but also philosophy, literature, or virtually any other genre of writing. The phrase Biblical exegesis can be used to distinguish studies of the Bible from other critical textual explanations.
Textual criticism investigates the history and origins of the text, but exegesis may include the study of the historical and cultural backgrounds of the author, text, and original audience. Other analyses include classification of the type of literary genres presented in the text and analysis of grammatical and syntactical features in the text itself.
One who practices exegesis is called an exegete (ˌɛksɪˈdʒiːt; from the Greek ἐξηγητής). The plural of exegesis is exegeses (ˌɛksɪˈdʒiːsiːz). Adjectives are exegetic or exegetical (e.g., exegetical commentaries). In biblical exegesis, the opposite of exegesis (to draw out) is eisegesis (to draw in), in the sense of an eisegetic commentator "importing" or "drawing in" their own subjective interpretations into the text, unsupported by the text itself. Eisegesis is often used as a derogatory term.
One of the early examples of exegesis, and one of the larger corpora of text commentaries from the ancient world, comes from Mesopotamia (modern day Iraq) in the first millennium BCE. Containing over 860 manuscripts, the majority of which date to 700–100 BCE, these commentaries explore numerous types of texts, including literary works (such as the Babylonian Epic of Creation), medical treatises, magical texts, ancient dictionaries, and law collections (the Code of Hammurabi). Most of them, however, comment on divination treatises, in particular treatises that predict the future from the appearance and movement of celestial bodies on the one hand (Enūma Anu Enlil), and from the appearance of a sacrificed sheep's liver on the other (Bārûtu).
