Final answer:
The ark in a synagogue contains sacred scriptures; the Torah scrolls, which are taken out and read to the congregation during services.
Step-by-step explanation:
The ark found in a synagogue contains sacred scriptures, specifically the Torah scrolls, which are the first five books of the Hebrew Bible. These scrolls are highly revered in Judaism and are kept in a special chest called a Torah ark when not in use. The ark is situated at the focal point of the synagogue. When it's time to read the scriptures, the scrolls are brought to the center of the synagogue, to a platform known as the bimah, and placed on a reading table to be read to the congregation.
