assembly, company, congregation, multitude, people, swarm

Boyd’s Bible Dictionary:

(collected together). Biblically, the Hebrew nationality (Num. 15:15). Generally, collected Jewry (Ex. 12:19). A popular assembly (Acts 19:32,39,41). A religious assembly, or church (Acts 7:38).

“Congregation” From Concise Bible Dictionary:

The term is constantly applied in the Old Testament to the community of Israel, and also to the actual assembling together of the people according to the unity of the congregation. Every descendant of the twelve tribes formed a part of that community. Those of other nations were received into the congregation on becoming PROSELYTES. The Ammonite and the Moabite were forbidden ever to come into the congregation of Jehovah, and there were a few other restrictions (Deut. 23:1-4). For various offenses an Israelite was cut off from the congregation (Exod. 12:19; Num. 9:13). See EXCOMMUNICATION.

“Assembly” From Concise Bible Dictionary:

Besides the use of this word for any collecting together, “as the assembly of the wicked,” it has a special reference in the Old Testament to the children of Israel as “the assembly,” whether they were collected together or not. Several Hebrew words are used, some implying “an appointed meeting,” others a “calling together.” “The whole assembly of the congregation” were to eat the passover (Ex. 12:6), though each family ate it in its own house. They accused Moses of having brought them into the wilderness to kill the “whole assembly with hunger,” (Ex. 16:3); so in many places. When they were especially called together to the feasts it is often called a SOLEMN ASSEMBLY, as in Leviticus 23:36; Numbers 29:35; Deuteronomy 16:8; 2 Kings 10:20; 2 Chronicles 7:9; Nehemiah 8:18.
In the New Testament the word is also used for any gathering of people, as at the tumult in Ephesus (Acts 19:32,39,41). In James 2:2 The word “assembly” is really the synagogue, or place of meeting. In Hebrews 12:23 the words “GENERAL ASSEMBLY” should be joined to Hebrews 12:22, reading “and to the innumerable company of angels, the general assembly:” the word “and” dividing the subjects. The Greek word used in Acts 19:32 is ἑκκλησἰα, and this often occurs in the New Testament where it is translated “church.” It signifies “called out,” and the church is a people called out by God to Himself from the mass of mankind. The church may more accurately be designated by the word “assembly.” See CHURCH.
