Exodus 8:4

And the frogs shall come up both on thee, and upon thy people,
and upon thy servants.
] No doubt by the interposition of divine power and providence, and it may be by the ministry of angels; so that let them use what care, caution, and diligence they would, there was no keeping them out; but they came upon all the people of the land, high and low, rich and poor, and upon the king's ministers, courtiers, and nobles, and the king himself not excepted; though by this particular enumeration of him, his people, and servants, the children of Israel may be thought to be exempted from this plague, as R. Japhez observes; though Aben Ezra dislikes his remark, but it seems to be just.
