In modern parlance, midrash (Hebrew root drš, “to investigate, seek, search out, examine”) refers to any act of interpretation, but in its strictest and most precise sense it refers to ancient rabbinic biblical interpretation. Midrash is both the process and product of interpretation contained in vast compilations of midrashim (plural) as well as in other rabbinic works such as the Talmud. Compendia of midrashim not only preserve interpretations and teachings but also reveal a curiously postmodern, polysemic approach to scriptural exegesis. These compilations are often categorized according to three (problematic) descriptive binaries: halakhic or aggadic; tannaitic (70–200 ce) or amoraic (200–500 ce); and exegetical or homiletical. Through the midrashic process, the Jewish sages of antiquity made the Bible relevant to their contemporaries, taught moral lessons, told fanciful stories, and developed as well as maintained theological beliefs and ethical codes of behavior. The study of midrash provides a portal into the cultural world of the rabbis of late antiquity; it also serves to highlight their approach to and assumptions about scripture, and their guiding hermeneutical practices and principles. Midrashic interpretation employs a variety of exegetical techniques that are often tightly connected to the language of scripture. In addition to wordplay, the rabbis occasionally use gematria, whereby the arithmetical value of Hebrew letters is used to interpret a word or verse. Intertextuality and the atomicization of scriptural words, phrases, and verses are fundamental characteristics of the midrashic method. Although the term midrash applies specifically to rabbinic biblical interpretation, it is sometimes used more broadly as a synonym for aggadah, which includes rabbinic stories, maxims, and parables. Critical editions of midrashic compilations as well as digital advancements and translations give scholars in cognate fields the necessary tools to understand rabbinic literature and undertake comparative studies.
