A gabbai (Hebrew: גבאי), also known as shamash שמש (sometimes spelled shamas) or warden (UK, similar to churchwarden) is a beadle or sexton, a person who assists in the running of synagogue services in some way. The role may be undertaken on a voluntary or paid basis. A shamash (literally "servant") can also mean an assistant to a rabbi (particularly the secretary or personal assistant to a Hassidic Rebbe).
The word gabbai, is Aramaic and, in Talmudic times, meant collector of taxes or charity, or treasurer.
While the specific set of duties vary from synagogue to synagogue, a gabbai's responsibilities will typically include ensuring that the religious services run smoothly.
The gabbai may be responsible for calling congregants up to the Torah. In some synagogues, the gabbai stands next to the Torah reader, holding a version of the text with vowels and trop markings (which are not present in the actual Torah scroll), following along in order to correct the reader if the reader makes an error. In other synagogues, these responsibilities are instead that of a sgan (סגן).
A gabbai might manage some of the financial affairs of the institution, such as collection of contributions and keeping financial records. The administrator of charitable funds might be called the gabbai tzedakah.
A gabbai's responsibilities might also include maintaining a Jewish cemetery.
In some parts of the world, the gabbaim will wear special clothing. In Anglo-Jewry, for example, gabbaim in some synagogue movements have traditionally worn top hats and where there is a shamash, he may wear canonicals.
