Talmud

Talmud is Hebrew for “learning,” appropriate for a text that people devote their lives to studying and mastering. The Talmud is a collection of writings that covers the full gamut of Jewish law and tradition, compiled and edited between the third and sixth centuries. Written in a mixture of Hebrew and Aramaic, it records the teachings and discussions of the great academies of the Holy Land and Babylonia.
