'Battering rams' in the Bible

And lay siege against it, and build a fort against it, and cast a mount against it; set the camp also against it, and set battering rams against it on every side.

At his right hand was the divination for Jerusalem, to appoint captains, to open the mouth in the slaughter, to lift up the voice with shouting, to appoint battering rams against the gates, to cast a mount, and to build a fort.
