Ksav Sofer notes that the parsha that speaks of the appointment of a king the Torah uses the singular voice: “Asima alay melech…. Som tasim alecha melech…” There is a din (O.C. 53:19) that when a congregation appoints a new chazzan, any single individual may object to the appointment (provided they can offer a legitimate reason for doing so). There has to be no dissension with respect to the final choice. So too, suggests the Ksav Sofer, when it comes to the appointment of a king, the people have to speak with unanimity, with one voice. There can be no objections to the selection.
I wonder if this reflects the reality. David haMelech was chased across the countryside by Shaul — it doesn’t seem that even he had the unanimous consent of the people, at least at the time of his appointment.
Why doesn’t this “reflect the reality”? Did anyone still have a “legitimate” objection against David?
