'Mounds' in the Bible

Pharaoh with his mighty army and great company will not help him in the war, when they cast up ramps and build siege walls to cut off many lives.

Into his right hand came the divination, ‘Jerusalem,’ to set battering rams, to open the mouth for slaughter, to lift up the voice with a battle cry, to set battering rams against the gates, to cast up ramps, to build a siege wall.
