Jewish skullcaps are also known as kippah, the hech cap, and most commonly the yarmulke. The sacred Jewish text of the Talmud dictates that people must "Cover their heads in order that the fear of heaven may be upon them." Also, Jewish law tells its followers that the kippah must be worn during all instances of prayer. Another important piece of Hebrew text known as the Shulchan Aruch expounds on this idea, explaining that Jewish men specifically are not to walk more than 4 cubits without having their head covered. The practice of covering one's head is said to "honor God", and not doing so is a sign of disrespect.
Original Meaning
Among less orthodox Jewish people, some contention has arisen regarding the actual practice of covering one's head. Some argue that many famous Rabbis’ were commonly seen without their head's concealed, which is the driving force behind the current Jewish leniency with regard to Jewish skullcaps. However, it is more common to instill the practice into young Jewish children, which allows them to retain it as they grow older. The original meaning wasn't to honor God as such, but to honor God in a way that shows that have a fear of Him. The thought of fearing God itself and the recognition the kippah offered is why they were and are fairly commonplace in Jewish communities.
Types of Kippah
Several different variations of the kippah are also used. It is interesting to note that different sects and practices of the Jewish faith tend to wear different types of head garb. For example, crocheted Jewish skullcaps are mainly used in Religious Zionism and Modern Orthodox, while more stylish Suede kippah are used by Conservative Judaists. Other types of Jewish skullcaps include black velvet, satin, and white crocheted. Burkharan kippah is also used, and is popular with small Jewish children, liberal leaning Jews, feminist, and reform Jews.
