'Works' in the Bible

So this is what the Lord says about the king of Assyria: "He will not enter this city, nor will he shoot an arrow here. He will not attack it with his shield-carrying warriors, nor will he build siege works against it.

Because they have forsaken me, and have burned incense unto other gods, that they might provoke me to anger with all the works of their hands; therefore my wrath shall be kindled against this place, and shall not be quenched.

Now in the ninth year of Zedekiah’s reign, on the tenth day of the tenth month, Nebuchadnezzar king of Babylon came, he with all his army, against Jerusalem, and camped against it and built siege works surrounding it.
