'Battering rams' in the Bible

Then lay siege against it, build a siege wall, raise a ramp against it; set up [enemy] camps and place battering rams all around it.

In his right hand is the lot marked for Jerusalem: to set battering rams, to open the mouth calling for destruction, to lift up the voice with a war cry, to set battering rams against the gates, to put up assault ramps, and to build siege walls.
