the Hebrew people collectively as a holy community (Numbers 15:15)
Every circumcised Hebrew from twenty years old and upward was a member of the congregation. Strangers resident in the land, if circumcised, were, with certain exceptions (Exodus 12:19; Numbers 9:14; Deuteronomy 23:1-3), admitted to the privileges of citizenship, and spoken of as members of the congregation (Exodus 12:19; Numbers 9:14; 15:15).
The congregation were summonded together by the sound of two silver trumpets, and they met at the door of the tabernacle (Numbers 10:3). These assemblies were convened for the purpose of engaging in solemn religious services (Exodus 12:27; Numbers 25:6; Joel 2:15), or of receiving new commandments (Exodus 19:7-8). The elders, who were summonded by the sound of one trumpet (Numbers 10:4), represented on various occasions the whole congregation (Exodus 3:16; 12:21; 17:5; 24:1).
After the conquest of Canaan, the people were assembled only on occasions of the highest national importance (Judges 20; 2 Chronicles 30:5; 34:29; 1 Samuel 10:17; 2 Samuel 5:1-5; 1 Kings 12:20; 2 Kings 11:19; 21:24; 23:30).
In subsequent times the congregation was represented by the Sanhedrim; and the name synagogue, applied in the Septuagint version exclusively to the congregation, came to be used to denote the places of worship established by the Jews.
