A synagogue is a place of Jewish worship, where Jews congregate and see their rabbi and practice the laws of the Torah. Sabbath, or Shabbat, is a weekly practice of rest that starts Friday at sundown and ends Saturday evening. During Shabbat, Jews light candles and observe the rest that G-d took on the seventh day of creating the world.
Kosher is a form of religious dietary restriction that Jews practice. It includes not mixing meats and milk, and not eating animals that have split hooves.
