'Battering rams' in the Bible

Lay siege to it! Build siege works against it. Erect a siege ramp against it! Post soldiers outside it and station battering rams around it.

Into his right hand comes the portent for Jerusalem -- to set up battering rams, to give the signal for slaughter, to shout out the battle cry, to set up battering rams against the gates, to erect a siege ramp, to build a siege wall.

He will direct the blows of his battering rams against your walls and tear down your towers with his weapons.
