Their land brought forth frogs in abundance, in the chambers of their kings.

Augustine of Hippo
AD 430
20. "He turned their waters into blood, and slew their fish" (ver. 29). "He made their land frogs, yea, even in the king's chambers" (ver. 30): as if he were to say, He turned their land into frogs. For there was so great a multitude of frogs, that this might well be said by hyperbole.
