'Public' in the Bible

Now in the first year of Cyrus, king of Persia, in order that the word of the Lord given by the mouth of Jeremiah might come true, the spirit of Cyrus, king of Persia, was moved by the Lord, so that he made a public statement through all his kingdom, and put it in writing, saying,

And they made a public statement through all Judah and Jerusalem, to all those who had come back, that they were to come together to Jerusalem;

Then all the men of Judah and Benjamin assembled in Jerusalem within the three days. It was the ninth month on the twentieth day of the month. All the people sat in the public square of the house of God trembling because of this matter and from the rains.
