'Something' in the Bible

Though our sins give witness against us, do something, O Lord, for the honour of your name: for again and again we have been turned away from you, we have done evil against you.

Will you get directions from the Lord for us; for Nebuchadrezzar, king of Babylon, is making war against us; it may be that the Lord will do something for us like all the wonders he has done, and make him go away from us.
