Plentiful as is the FROG throughout Egypt, Palestine, and Syria, it is very remarkable that in the whole of the canonical books of the Old Testament the word is only mentioned thrice, and each case in connexion with the same event. In Exod. viii. we find that the second of the plagues which visited Egypt came out of the Nile, the sacred river, in the form of innumerable Frogs. The reader will probably remark, on perusing the consecutive account of these plagues, that the two first plagues were connected with that river, and that they were foreshadowed by the transformation of Aaron's rod. When Moses and Aaron appeared before Pharaoh to ask him to let the people go, Pharaoh demanded a miracle from them, as had been foretold. Following the divine command, Aaron threw down his rod, which was changed into a serpent. Next, as was most appropriate, came a transformation wrought on the river by means of the same rod which had been transformed into a Serpent, the whole of the fresh-water throughout the land being turned into blood, and the fish dying and polluting the venerated river with their putrefying bodies. In Egypt, a partially rainless country, such a calamity as this was doubly terrible, as it at the same time desecrated the object of their worship, and menaced them with perishing by thirst. The next plague had also its origin in the river, but extended far beyond the limits of its banks. The frogs, being unable to return to the contaminated stream wherein they had lived, spread themselves in all directions, so as to fulfil the words of the prediction: "If thou refuse to let them go, behold, I will smite all thy borders with frogs: "And the river shall bring forth frogs abundantly, which shall go up and come into thine house, and into thy bed-chamber, and upon thy bed, and into the house of thy servants, and upon thy people, and into thine ovens, and into thy kneading-troughs" (or dough). Supposing that such a plague was to come upon us at the present day, we should consider it to be a terrible annoyance, yet scarcely worthy of the name of plague, and certainly not to be classed with the turning of a river into blood, with the hail and lightning that destroyed the crops and cattle, and with the simultaneous death of the first-born. But the Egyptians suffered most keenly from the infliction. They were a singularly fastidious people, and abhorred the contact of anything that they held to be unclean. We may well realize, therefore, the effect of a visitation of Frogs, which rendered their houses unclean by entering them, and themselves unclean by leaping upon them; which deprived them of rest by getting on their beds, and of food by crawling into their ovens and upon the dough in the kneading-troughs.
