Charles H. Spurgeon on Psalms 105:30

Their land brought forth frogs in abundance. This is the natural appearance next in the order of occurrence to the Red Nile, and of it also the God of nature availed himself to vindicate his power before Pharaoh, and before Egypt. The Nile, its branches, and the great canals of irrigation are all bank full, and the exuberant moisture has aroused from their summer torpor, into life and activity, the frogs of the Nile, in numbers inconceivable to those who have not been in hot countries. Even in ordinary years the annoyance of these loathsome creatures night and day, gives some idea of what this plague must have been, and renders abundantly reasonable the creation of a goddess, Ranipula, {1} at the very commencement of the mythology of ancient Egypt. In the whole of this fearful succession of judgments there is not one more personally revolting than the plague of frogs. William Osborne. {1} "Driver away of frogs." Her name was Heki; Birch ap. Bunsen. She was the Buto of the Greek authors.
