Exodus 8:4 - John Gill's Exposition of the Entire Bible

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.
