'Assembly' in the Bible

Now while Ezra was praying and confessing, weeping and laying himself face down before the house of God, a very large group from Israel, of men, women, and children, gathered to him, for the people wept bitterly.

and that whoever would not come within three days, by order of the counsel of the leaders and the elders, all his possessions and property would be forfeited and he himself would be excluded from the assembly of the exiles.

Then all the assembly replied with a loud voice, “It is our responsibility to do just as you have said.

Let our leaders stand for and represent the entire assembly; let all those in our cities who have married foreign wives come at appointed times, together with the elders and judges of each city, until the burning anger of our God over this matter is turned away from us.”
