Ezra 10:7-9

7They made a proclamation throughout Judah and Jerusalem to all the exiles, that they should assemble at Jerusalem, 8and that whoever would not come within three days, according to the counsel of the leaders and the elders, all his possessions should be forfeited and he himself excluded from the assembly of the exiles.

9So 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 open square before the house of God, 1trembling because of this matter and the heavy rain.
