of a record of rabbinic discussions pertaining to Jewish law, ethics, philosophy, customs, and history. The Talmud has two components: the Mishnah (c. 200 AD), the first written compendium of Judaism's oral Law; and the Gemara (c. 500 AD), an elucidation of the Mishnah and related Tannaitic writings that often ventures onto other subjects and expounds broadly on the Tanakh. There are numerous citations of Sirach within the Talmud, even though the book was not ultimately accepted into the Hebrew canon. The Talmud is the basis for all codes of rabbinic law and is often quoted in other rabbinic literature. Certain groups of Jews, such as the Karaites, do not accept the Oral Law as it is codified in the Talmud and only consider the Tanakh to be authoritative. Samaritan canon Another version of the Torah, in the Samaritan alphabet, also exists. This text is associated with the Samaritans (Hebrew: שומרונים; Arabic: السامريون), a people of whom the Jewish Encyclopedia states: "Their history as a distinct community begins with the taking of Samaria by the Assyrians in 722 BC." The Samaritan Pentateuch's relationship to the Masoretic Text is still disputed. Some differences are minor, such as the ages of different people mentioned in genealogy, while others are major, such as a commandment to be monogamous, which appears only in the Samaritan version. More importantly, the Samaritan text also diverges from the Masoretic in stating that Moses received the Ten Commandments on Mount Gerizim—not Mount Sinai—and that it is upon Mount Gerizim that sacrifices to God should be made—not in Jerusalem. Scholars nonetheless consult the Samaritan version when trying to determine the meaning of text of the original Pentateuch, as well as to trace the development of text-families. Some scrolls among the Dead Sea scrolls have been identified as proto-Samaritan Pentateuch text-type. Samaritans consider the Torah to be inspired scripture, but do not accept any other parts of the Bible—probably a position also held by the Sadducees. They did not expand their canon by adding any Samaritan compositions. There is a Samaritan Book of Joshua; however, this is a popular chronicle written in Arabic and is not considered to be scripture. Other non-canonical Samaritan religious texts include the Memar Markah ("Teaching of Markah") and the Defter (Prayerbook)—both from the 4th century or later. The people of the remnants of the Samaritans in modern-day Israel/Palestine retain their version of the Torah as
