What is the house of worship for Judaism?

In Judaism a house of worship is called a synagogue. The word itself is of Greek origin, and means "assembly.'" In Hebrew, a synagogue is known as either a "bet kenesset"(house of assembly) or "bet tefila" (house of prayer). Synagogues are among the oldest known places of religious worship, first established several thousand years ago. As well as being places for prayer, synagogues are also regularly used for religious reading and study. They can also serve as focal points for the local Jewish community, providing facilities such as catering halls, libraries, and day care centers.
Whatever function a synagogue serves, its most sacred spot is the Torah Ark, a cabinet in which the scrolls of the Torah, the Jewish book of scripture, are kept. The Torah Ark replicates the Ark of the Covenant, which held the tablets given to Moses by God, and on which were inscribed the Ten Commandments.
