Symbolic Explanations

Star  of David
The Star of David is called the Shield of David in Hebrew. It is named after King David of ancient Israel; sometimes it is called the Seal of Solomon after his son, King Solomon. The number seven has religious significance in Judaism, e.g., the six days of Creation plus the seventh day of rest, the six working days in the week plus Shabbat, the Seven Spirits of God, as well as the Menorah in the ancient Temple, whose seven oillamps rest on three stems branching from each side of a central pole. And so on. Perhaps, the Star of David came to be used as a standard symbol in synagogues because its organization into 3+3+1 corresponds to the Temple's Menorah, which was the more traditional symbol for Judaism in ancient times.It is a generally recognized symbol of Judaism and Jewish identity and is also known colloquially as the Jewish Star. Its usage as a symbol of Judaism and Jewish identity began in the Middle Ages, alongside the more ancient symbol of the menorah. This six pointed star is the premier symbol of Judaism. In 1897, it was adopted as the symbol for the First Zionist Congress, and, in 1948, it became the central figure in the flag of the state of Israel.
The Hebrew word Mezuzah, which literally means "door post" is the word that appears in the Torah text"..write (this command-the Shema) on the mezuzah (door post) of your house and upon your gates.The Mezuzah is comprised of two parts: the container or box, and the parchment. The container may be made of any kind of material and is inscribed with the Hebrew letter "shin", a symbol of the Divine (the first Hebrew letter of Shaddai). Therefore when a Jewish family places the mezuzah on their dwelling, they are in effect Jewish law) prescribes in detail the affixingplacing the name of God, El Shaddai, at every entry to their dwelling. The second and most important part of the mezuzah is called the klaf (parchment) on which is inscribed by hand in Hebrew the words of the commandment in Deuteronomy 6:4-9 which begins "Hear O Israel the Lord our God, the Lord is One" The mezuzah silently declares "You are under the authority of the Torah, and wherever you may be, your life must demonstrate God's righteousness and holiness, the intergrity of His morality."(Jewish law) prescribes in detail the affixing of mezuzot on doorposts. Since almost every Jewish home has a mezuzah on its front doorpost, it has historically been a way of recognizing a Jewish home.
One of the oldest symbols of the Jewish faith is the menorah, a seven-branched candelabrum used in the Temple. The kohanim lit the menorah in the Sanctuary every evening and cleaned it out every morning, replacing the wicks and putting fresh olive oil into the cups. The illustration at left is based on instructions for construction of the menorah found in Exodus 25:31-40.

It has been said that the menorah is a symbol of the nation of Israel and our mission to be "a light unto the nations." (Isaiah 42:6). The sages emphasize that light is not a violent force; Israel is to accomplish its mission by setting an example, not by using force. This idea is highlighted in the vision in Zechariah 4:1-6. Zechariah sees a menorah, and G-d explains: "Not by might, nor by power, but by My spirit."

The lamp stand in today's synagogues, called the ner tamid (lit. the continual lamp; usually translated as the eternal flame), symbolizes the menorah.

The nine-branched menorah used on Chanukah is commonly patterned after this menorah, because Chanukah commemorates the miracle that a day's worth of oil for this menorah lasted eight days.

The menorah in the First and Second Temples had seven branches. After the Temples were destroyed, a tradition developed not to duplicate anything from the Temple and therefore menorah's no longer had seven branches. The use of six-branched menoras became popular, but, in modern times, some rabbis have gone back to the seven-branched menoras, arguing that they are not the same as those used in the Temple because today's are electrified.
The shofar in the Temple in Jerusalem was generally associated with the trumpet; and both instruments were used together on various occasions. On New-Year's Day the principal ceremony was conducted with the shofar, which instrument was placed in the center with a trumpet on either side; it was the horn of a wild goat and straight in shape, being ornamented with gold at the mouthpiece. On fast-days the principal ceremony was conducted with the trumpets in the center and with a shofar on either side. On those occasions the shofarot were rams' horns curved in shape and ornamented with silver at the mouthpieces. On Yom Kippur of the jubilee year the ceremony was performed with the shofar as on New-Year's Day.

The shofar was blown in the times of Joshua to help him capture Jericho. As they surrounded the walls the shofar was blown and the Jews were able to capture the city. The shofar was commonly taken out to war so the troops would know when a battle would begin. The person who would blow the shofar would call out to the troops from atop a hill. All of the troops were able to hear the call of the shofar from their position because of its distinct noise.
This symbol commonly worn as jewelry is simply the Hebrew word Chai life)The word "chai"has great significance to Judaism which is very focused on "life"'

In Judaism, the Chai symbol consists of the letters of the Hebrew alphabet Het (ח) and Yod (י). In the Hebrew language, the word chai (חי) spelled by these two letters means "living", and is related to the word for "life", chaim, and also appears in the slogan am yisrael chai (עם ישראל חי, "The people of Israel live!", referring to all Jews). There have been various mystical numerological speculations about the fact that according to the system of gematria, the letters of chai add up to 18 (see "Jewish use of the Tetragrammaton" and "Lamedvavniks"). For this reason, 18 is a lucky number in Judaism, and many Jews give gifts of money in multiples of 18 as a result.

The Chai symbol is often worn by Jews as a medallion around the neck (along with the Magen David or Star of David and the Chamesh).
The Wailing Wall
his is the "Wailing Wall" where people from all over the world come to pray and touch the wall. The Western Wall or simply The Kotel, is a retaining wall in Jerusalem that dates from the time of the Jewish Second Temple. It is sometimes referred to as the Wailing Wall, or as the al-Buraq Wall, in a mix of English and Arabic. The Temple was the most sacred building in Judaism. Herod the Great built vast retaining walls around Mount Moriah, expanding the small, quasi-natural plateau on which the First and Second Temples stood into the wide open spaces of the Temple Mount seen today.
