'Battering rams' in the Bible

and lay siege against it, and build forts against it, and cast a mound against it, and set camps against it, and place battering-rams against it round about.

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.
