and come in do all the heads of the king of Babylon, and they sit at the middle gate, Nergal-Sharezer, Samgar-Nebo, Sarsechim, chief of the eunuchs, Nergal-Sharezer, chief of the Mages, and all the rest of the heads of the king of Babylon.

And Nebuzar-Adan, chief of the executioners sendeth, and Nebushazban, chief of the eunuchs, and Nergal-Sharezer, chief of the Mages, and all the chiefs of the king of Babylon;
