MamzerIn the Hebrew Bible and Jewish religious law, a mamzer (ממזר, (), "estranged person"; plural mamzerim) is a person who is born as the result of certain forbidden relationships or incest (as it is defined by the Bible), or the descendant of such a person. Mamzer status (mamzerut) is not synonymous with the traditional western definition of illegitimacy, since it does not include children born to unmarried mothers. Some have explained the word mamzer as the masculine noun form derived from the root m-z-r, having a meaning of spoilt/corrupt.
613 commandmentsAccording to Jewish tradition, the Torah contains 613 commandments (taryag mitzvot). This tradition is first recorded in the 3rd century CE, when Rabbi Simlai mentioned it in a sermon that is recorded in Talmud Makkot 23b. Other classical sages who hold this view include Rabbi Simeon ben Azzai and Rabbi Eleazar ben Yose the Galilean. It is quoted in Midrash Exodus Rabbah 33:7, Numbers Rabbah 13:15–16; 18:21 and Talmud Yevamot 47b.
MitzvahIn its primary meaning, the Hebrew word (ˈmɪtsvə; מִצְוָה, mīṣvā mit͡sˈva, plural מִצְווֹת mīṣvōt mit͡sˈvot; "commandment") refers to a commandment commanded by God to be performed as a religious duty. Jewish law () in large part consists of discussion of these commandments. According to religious tradition, there are 613 such commandments. In its secondary meaning, the word mitzvah refers to a deed performed in order to fulfill such a commandment. As such, the term mitzvah has also come to express an individual act of human kindness in keeping with the law.
KohenKohen (, kōhēn, koˈ(h)en, "priest", pl. , kōhănīm, koˈ(h)anim, "priests") is the Hebrew word for "priest", used in reference to the Aaronic priesthood, also called Aaronites or Aaronides. They are traditionally believed and halakhically required to be of direct patrilineal descent from the biblical Aaron (also Aharon), brother of Moses, and thus belong to the Tribe of Levi. During the existence of the Temple in Jerusalem (and previously the Tabernacle), kohanim performed the Temple sacrificial offerings, which were only permitted to be offered by them.
RabbiA rabbi (ˈræbaɪ) is a spiritual leader or religious teacher in Judaism. One becomes a rabbi by being ordained by another rabbi—known as semikha—following a course of study of Jewish history and texts such as the Talmud. The basic form of the rabbi developed in the Pharisaic (167 BCE–73 CE) and Talmudic (70–640 CE) eras, when learned teachers assembled to codify Judaism's written and oral laws. The title "rabbi" was first used in the first century CE.
PhariseesThe Pharisees (ˈfærəsiːz; Pərūšīm) were a Jewish social movement and a school of thought in the Levant during the time of Second Temple Judaism. After the destruction of the Second Temple in 70 CE, Pharisaic beliefs became the foundational, liturgical, and ritualistic basis for Rabbinic Judaism. Conflicts between Pharisees and Sadducees took place in the context of much broader and longstanding social and religious conflicts among Jews, made worse by the Roman conquest.
TannaimTannaim (Amoraic Hebrew: תנאים tannaˈ(ʔ)im, singular tanˈna, Tanna "repeaters", "teachers") were the rabbinic sages whose views are recorded in the Mishnah, from approximately 10–220 CE. The period of the Tannaim, also referred to as the Mishnaic period, lasted about 210 years. It came after the period of the Zugot ("pairs"), and was immediately followed by the period of the Amoraim ("interpreters"). The root tanna () is the Talmudic Aramaic equivalent for the Hebrew root shanah (), which also is the root-word of Mishnah.
AmidahThe Amidah (תפילת העמידה, Tefilat HaAmidah, 'The Standing Prayer'), also called the Shemoneh Esreh (שמנה עשרה 'eighteen'), is the central prayer of the Jewish liturgy. Observant Jews recite the Amidah at each of three daily prayer services in a typical weekday: morning (Shacharit), afternoon (Mincha), and evening (Ma'ariv). On Shabbat, Rosh Chodesh, and Jewish festivals, a fourth Amidah (Mussaf) is recited after the morning Torah reading, and once per year a fifth Amidah (Ne'ilah) is recited, around sunset on Yom Kippur.
