'Mounds' in the Bible

Behold the mounds, they are come unto the city for taking it; and the city is given over into the hand of the Chaldeans, that fight against it, by the sword, and the famine, and the pestilence: and what thou hast spoken is come to pass; and behold, thou seest it.

For thus saith Jehovah the God of Israel concerning the houses of this city, and concerning the houses of the kings of Judah, which are thrown down because of the mounds and because of the sword:

Come against her from the most distant places.Open her granaries;pile her up like mounds of grainand completely destroy her.Leave her no survivors.

Now it came about in the ninth year of his reign, in the tenth month, on the tenth day, Nebuchadnezzar king of Babylon came, he and all his army, against Jerusalem; and they camped against it and built moveable towers and siege mounds all around it.
