Quoting Commentary for II Kings 20:18

AGAINST TWO ‘SARISAV’ (OF HIS EUNUCHS). These two lords were both castrates, for as they also acted as the chiefs of the butlers and bakers in the women’s quarters in the royal apartments, the kings would customarily castrate them. Onkelos’ opinion though is that sarisim means lords and chiefs. Thus he says of Potiphar, who is called sris par’oh,²⁴¹Above, 37:36. “the officer of Pharaoh,” and in the present verse he similarly translates, “against his two officers.” And so did the Targum Yonathan translate: And they shall be ‘sarisim’ in the palace of the king of Babylon.²⁵⁶II Kings 20:18. Yonathan translated this as: “And they shall be officers.”
