'Mounds' in the Bible

See the siege ramps [of mounded earth that the enemy has built against the walls]; they have come up to the city to capture it. And the city is given into the hand of the Chaldeans [of Babylon] who fight against it, because of the sword, the famine and the virulent disease [that have overcome the people]. What You have spoken has come to pass, and behold, You see it.

For thus says the Lord, the God of Israel, concerning the houses of this city and the houses of the kings of Judah which are torn down to make a defense against the siege ramps and against the sword,

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.
