The scriptural texts for tefillin are obscure in literal meaning. For example, the verse in Deut. 11:18 does not designate what specifically to "bind upon your arm," and the definition of totafot is not obvious. It is the Talmud, the authoritative oral tradition for Rabbinic Judaism, which explains what are to be bound to the body and the form of tefillin.
Shofar: The shofar is mentioned frequently in the Hebrew Bible, the Talmud and rabbinic literature. The blast of a shofar emanating from the thick cloud on Mount Sinai made the Israelites tremble in awe (Exodus 19:16).

The festival is observed by the kindling of the lights of a unique candelabrum, the nine-branched Menorah or Hanukiah, one additional light on each night of the holiday, progressing to eight on the final night. The typical Menorah consists of eight branches with an additional raised branch. The extra light is called a shamash and is given a distinct location, usually above or below the rest. The purpose of the shamash is to have a light available for use, as using the Hanukkah lights themselves is forbidden.
Kashrut: Kashrut is the set of Jewish dietary laws. Food that may be consumed according to halakha (Jewish law) is termed kosher in English, from the Ashkenazi pronunciation of the Hebrew term kashér , meaning "fit" (in this context, fit for consumption). Food that is not in accordance with Jewish law is called treif . Kosher can also refer to anything that is fit for use or correct according to halakha, such as a hanukiyah (candelabra for Hannukah), or a sukkah (a Sukkot booth). The word kosher has become English vernacular, a colloquialism meaning proper, legitimate, genuine, fair, or acceptable.
Among the numerous laws that form part of kashrut are the prohibitions on the consumption of unclean animals (such as pork, shellfish (both Mollusca and Crustacea) and most insects, with the exception of crickets and locusts), mixtures of meat and milk, and the commandment to slaughter mammals and birds according to a process known as shechita. Most of the basic laws of kashrut are derived from the Torah's Books of Leviticus and Deuteronomy. Their details and practical application, however, is set down in the oral law (eventually codified in the Mishnah and Talmud) and elaborated on in the later rabbinical literature. While the Torah does not state the rationale for most kashrut laws, many reasons have been suggested, including philosophical, practical and hygienic.
Tzedakah, or Ṣ'daqah in Classical Hebrew, is a Hebrew word literally meaning righteousness but commonly used to signify charity. It is based on the Hebrew word meaning righteousness, fairness or justice, and it is related to the Hebrew word Tzadik meaning righteous as an adjective (or righteous individual as a noun in the form of a substantive). In Judaism, tzedakah refers to the religious obligation to do what is right and just, which Judaism emphasises are important parts of living a spiritual life.
Sabbath or a sabbath is generally a weekly day of rest or time of worship observed in Abrahamic religions and other practices. Many viewpoints and definitions have arisen over the millennia. The term has been used to describe a similar weekly observance in any of several other traditions; the new moon; any of seven annual festivals in Judaism and some Christian traditions; any of eight annual pagan festivals (usually "sabbat"); an annual secular holiday; and a year of rest in religious or secular usage, originally every seventh year.
