'Proclaimed a Fast' in the Bible

I proclaimed a fast there at the river Ahava to humble ourselves before our God in order to seek from him a safe journey for us, our children, and our possessions.

{And then} in the fifth year of Jehoiakim, the son of Josiah, the king of Judah, in the ninth month, all the people in Jerusalem and all the people who came from the towns of Judah to Jerusalem proclaimed a fast {before} Yahweh.

And the people of Nineveh believed in God, and they proclaimed a fast and put on sackcloth--from the greatest of them {to the least important}.
