Chai is the Hebrew word for life, it consists of two Hebrew letters—chet and yud. This is a Jewish symbol that frequently appears on pendants and other jewelry. Chai also refers to the number 18 because each Hebrew letter has a numerical equivalent which is considered a special number in Jewish tradition.
o Kippah is a clothing worn by Jews which varies according to the denomination of Judaism they adhere to. Orthodox Jewish men always wear a kippah while Liberal or Reform Jews consider it optional, but most Jews will cover their heads when praying, and etc. This head covering is a sign of respect and fear of God, and it separates God and human, by wearing a hat you are recognizing that God is above all mankind. Many Jews feel that by wearing a kippah they are proudly announcing to the world that they are Jewish.
o Dreidel is a spinning top, with four sides, each marked with a different Hebrew letter (nun, gimel, hay, and shin). Playing dreidel on Hanukkah is based on a legend that, during the time of the Maccabees, when Jewish children were forbidden from studying Torah, yet they studied it anyways. When a Greek official would come close they would put away their books and take out spinning tops, claiming they were just playing games. The letters on the dreidel are the first letters in a Hebrew phrase that means “A Great Miracle Happened There” (There being the land of Israel).
o Menorah(Hanukkah Menorah) is a nine-stemmed candelabra (eight flames plus one shamash also know as a “helper candle”) used on Hanukkah. This is different from the seven-candled Menorah used in the ancient temple in Jerusalem, the hannukiyah symbolizes the miracle of the holiday, when an amount of oil suitable for one day of light burned for eight days.
o Mezuzah is a small box placed on the right doorpost of Jewish homes, and inside the box is a scroll with verses from the Torah and the Shema prayer inscribed on it. This concept of a mezuzah comes from the Torah, where we read, “And you shall inscribe them on the doorposts (mezuzot) of your house and on your gates”. Some people believe that the mezuzah provides special protection over the residents of the home where it hangs, and when they pass by it some people touch the mezuzah with their hand, then kiss their hand.
o Shofar is a ram’s horn that is blown like a trumpet, it makes four sounds: tekiah, shevarim, teruah, and tekiah gedolah which remind many people of a crying voice. Hearing the shofar’s call is a reminder for us to look inward and repent for the sins of the past year. It calls to mind the image of the ram stuck in the bush that Abraham ultimately sacrificed instead of his son — reflecting our own sometimes difficult parent-child relationship with God. The most common place to hear the Shofar is in the synagogue especially if you attend for the High Holidays shofar is blown on Rosh Hashanah and Yom Kippur, yet the it is not to be blown on Shabbat.
o Star of David is a symbol commonly associated with Judaism and the Jewish people. The double triangle of the Star of David symbolizes the connection of both the Torah and Israel. The Star of David is an important symbol of the Jew and the Jewish people, but it is just that: a symbol. We have to live, think, and behave as a Jew. We can do this by putting a mezuzah on your door, study some Torah, eat kosher food, welcome the Shabbat with candles and a festive meal, and you’ve will become a living Star of David.
o Tallit soma prayer shawl made from wool, cotton, or synthetic fibers traditionally worn during morning prayers. In Orthodox communities, a tallit is traditionally worn by me, though women in non-Orthodox congregations — and sometimes in Orthodox partnership minyans — wear them as well as a matter of personal choice. Tzitzit are the tassels affixed to the four corners of a tallit, and they are also sometimes s affixed to a four-cornered undergarment that is also called a tzitzit. The practice of wearing a tzitzit, traditional by men, is biblical in origin.
Tefillin (aka phylacteries) are cubic black leather boxes with leather straps that Orthodox Jewish men wear on their head and their arm during weekday prayer. The boxes contain four hand-written texts from the Bible (Exodus 13:1-10, 13:11-16; Dueteronomy 6:4-9, 11:12-21) in which believers are common to wear certain words on the hand and between the eyes. The arm tefillin is put on first, on the upper part of the weaker arm, and a blessing is recited and the strap wrapped round the arm seven times.The blessing:“Blessed are You, Lord our God, King of the universe, who has sanctified us with His commandments and commanded us to put on Tefillin.” The head tefillin is loosely fastened on the head about one centimeter above a person's original hairline. A blessing is recited and the strap is tightened with the knot at the back of the head.The strap of the hand tefillin is then wound three times around the middle finger while reciting Hosea 2:21-2.
o Torah Scroll is the five Books of Moses (alternatively the Pentateuch, or Chumash in Hebrew) written on parchment that is read aloud in synagogues on Shabbat and holidays. Yad is a pointer, commonly made of metal or word, that is used by the synagogue Torah reader to keep place in the Scroll.
