Seven pillars to Judaism

A mezuzah is affixed to the doorframe in Jewish homes to fulfill the mitzvah (Biblical commandment) to inscribe the words of the Shema "on the doorposts of your house" (Deuteronomy 6:9). Some interpret Jewish law to require a mezuzah on every doorway in the home apart from bathrooms, and closets too small to qualify as rooms. The parchment is prepared by a qualified scribe (a "sofer stam") who has undergone many years of meticulous training, and the verses are written in black indelible ink with a special quill pen. The parchment is then rolled up and placed inside the case. 

Tefillin are a set of small black leather boxes containing scrolls of parchment inscribed with verses from the Torah, which are worn by observant Jews during weekday morning prayers. Although "tefillin" is technically the plural form (the singular being "tefillah"), it is loosely used as a singular as well. The hand-tefillin, or shel yad, is placed on the upper arm, and the strap wrapped around the arm, hand and fingers; while the head-tefillin, or shel rosh, is placed above the forehead. The Torah commands that they should be worn to serve as a "sign" and "remembrance" that God brought the children of Israel out of Egypt.

A shofar (Hebrew: שופר‎) is a horn, traditionally that of a ram, used for Jewish religious purposes. Shofar-blowing is incorporated in synagogue services on Rosh Hashanah and Yom Kippur. Shofar come in a variety of sizes. 

Hanukkah (Hebrew: חֲנֻכָּה‎‎, Tiberian: Ḥănukkāh, usually spelled חנוכה, pronounced [χanuˈka] in Modern Hebrew; a transliteration also romanized asChanukah, Chanukkah or Chanuka), also known as the Festival of Lights, is an eight-day Jewish holiday commemorating the rededication of theHoly Temple (the Second Temple) in Jerusalem at the time of the Maccabean Revolt of the 2nd century BCE. Hanukkah is observed for eight nights and days, starting on the 25th day of Kislev according to the Hebrew calendar, which may occur at any time from late November to late December in the Gregorian calendar.

Kosher foods are those that conform to the regulations of kashrut (Jewish dietary law). Food that may be consumed according to halakha (Jewish law) is termed kosher in English, from the Ashkenazi pronunciation of the Hebrew term kashér (כָּשֵׁר), meaning "fit" (in this context, fit for consumption). Food that is not in accordance with Jewish law is called treif (Yiddish: טרײף or treyf, derived from Hebrew טְרֵפָה trēfáh).

Tzedakah, or Ṣ'daqah in Classical Hebrew (Hebrew: צדקה‎; Arabic: صدقة‎), is a Hebrew word literally meaning righteousness but commonly used to signify charity. It is based on the Hebrew word (צדק, Tzedek) 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.
