'Assembly' in the Bible

‘Now if the whole congregation of Israel commits error and the matter escapes the notice of the assembly, and they commit any of the things which the Lord has commanded not to be done, and they become guilty;

when the sin which they have committed becomes known, then the assembly shall offer a bull of the herd for a sin offering and bring it before the tent of meeting.

Then he is to bring out the bull to a place outside the camp and burn it as he burned the first bull; it is the sin offering for the assembly.

When he goes in to make atonement in the holy place, no one shall be in the tent of meeting until he comes out, that he may make atonement for himself and for his household and for all the assembly of Israel.

and make atonement for the holy sanctuary, and he shall make atonement for the tent of meeting and for the altar. He shall also make atonement for the priests and for all the people of the assembly.

For seven days you shall present an offering by fire to the Lord. On the eighth day you shall have a holy convocation and present an offering by fire to the Lord; it is an assembly. You shall do no laborious work.
