And Ezra gave praise to the Lord, the great God. And all the people in answer said, So be it, so be it; lifting up their hands; and with bent heads they gave worship to the Lord, going down on their faces to the earth.

You are the Lord, even you only; you have made heaven, the heaven of heavens with all their armies, the earth and all things in it, the seas and everything in them; and you keep them from destruction: and the armies of heaven are your worshippers.
