Their land brought forth frogs in abundance, in the chambers of their kings.
Ver. 30. The land brought forth frogs in abundance] Like grass that grows upon the ground, or as fishes spawned in the sea, as the word signifieth, Genesis 1:20. Some think they were not common frogs, sed venenatas et horrendas, quales sunt rubetae et bufones, but toads and lizards; crocodiles, some think, came out of the river, and destroyed people (Aben-Ezra).
In the chambers of their kings] Regis et regulorum inter medias enses, medias custodias; this was the finger of God; as it was likewise when a town in Spain was overturned by conies, and another in Thessaly by moles, a city in France undone by frogs, and another in Africa by locusts (Plin. l. viii. c. 29).
