Ezra 10:5-9

Then Ezra stood and made the leading priests, the Levites, and all Israel take an oath that they would do according to this proposal; so they took the oath.

Then Ezra rose from before the house of God and went into the chamber of Jehohanan the son of Eliashib. Although he went there, he did not eat bread nor drink water, because he was mourning over the unfaithfulness of the exiles.

So they made a proclamation throughout Judah and Jerusalem to all the exiles, that they were to assemble at Jerusalem,

and that whoever did not come within three days, in accordance with the counsel of the leaders and the elders, all his property would be forfeited, and he himself would be excluded from the assembly of the exiles.

So all the men of Judah and Benjamin assembled at Jerusalem within the three days. It was the ninth month on the twentieth of the month, and all the people sat in the public square before the house of God, trembling because of this matter and the heavy rain.
