'Besieging' in the Bible

And Nebuchadnezzar king of Babylon came unto the city, while his servants were besieging it;

Now at that time the king of Babylon's army was besieging Jerusalem; and Jeremiah the prophet was shut up in the court of the guard, which was in the king of Judah's house.

And Pharaoh's army was come forth out of Egypt; and when the Chaldeans that were besieging Jerusalem heard tidings of them, they brake up from Jerusalem.
