Jewish faith. please can some tell me what...........

[2shoes]

skull caps are for and what they symbolise

www.jewishvirtuallibrary.org/jsource/Judaism/Kippah.html for more info.

just generally it's a sign of respect for god. they are more usually known as kippahs or yarmulkes.

very religious people would wear one all the time (or possibly another head covering like a baseball cap), less religious people would just wear one for synagogue services.
