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.
Berean Study Bible (BSB) - Ezekiel 21:22 >In his right hand appears the portent for Jerusalem, where he is to set up battering rams, to call for the slaughter, to lift a battle cry, to direct the battering rams against the gates, to build a ramp, and to erect a siege wall.
