'Battering rams' in the Bible

And lay siege against it, and build a siege wall against it, and cast up a mound against it; set camps also against it, and place battering rams against it round about.

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 set battering rams against the gates, to cast up a siege mound, and to build a wall.

And he shall set battering rams against your walls, and with his axes he shall break down your towers.
