We have here the starting of a matter perfectly new and surprising, which was the setting up of kingly government in Israel. Perhaps the thing had been often talked of among them by those that were given to change and affected that which looked great. But we do not find that it was ever till now publicly proposed and debated.

But the thing displeased Samuel,.... Not that they called him an old man, and suggested that he was incapacitated for his office, nor for observing the unbecoming walk of his sons, but for what follows: when they said, give us a king to judge us; what displeased him was, that they were for changing their form of government, not only to remove it from him...

the thing displeased Samuel when they said, Give us a king to judge us--Personal and family feelings might affect his views of this public movement. But his dissatisfaction arose principally from the proposed change being revolutionary in its character. Though it would not entirely subvert their theocratic government, the appointment of a visible monarch would necessarily tend to throw out of view their unseen King and Head.
