'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:

Neither shall Pharaoh with a mighty army and a great assemblage do anything for him in the war, when they cast up mounds and build forts to cut off many persons.

In his right hand is the lot of Jerusalem to appoint battering-rams, to open the mouth for bloodshed, to lift up the voice with shouting, to appoint battering-rams against the gates, to cast mounds, to build siege-towers.
