Because they had said to the Israelites, "Go and sweep and clean our houses, our courtyards, and our streets," He changed the dust of the air into lice, so that the vermin lay piled up in heaps an ell high, and when the Egyptians put on fresh garments, they were at once infested with the insects. The fourth plague was an invasion of the land by hordes of all sorts of wild animals, lions, wolves, panthers, bears, and others. They overran the houses of the Egyptians, and when they closed their doors to keep them out, God caused a little animal to come forth from the ground, and it got in through the windows, and split open the doors, and made a way for the bears, panthers, lions, and wolves, which swarmed in and devoured the people down to the infants in their cradles. If an Egyptian entrusted his ten children to an Israelite, to take a walk with them, a lion would come and snatch away one of the children, a bear would carry off the second, a serpent the third, and so on, and in the end the Israelite returned home alone. This plague was brought upon them because they were in the habit of bidding the Israelites go and catch wolves and lions for their circuses, and they sent them on such errands, to make them take up their abode in distant deserts, where they would be separated from their wives, and could not propagate their race. Then God brought a grievous murrain upon their cattle, because they had pressed the Israelites into their service as shepherds, and assigned remote pasturing places to them, to keep them away from their wives. Therefore the murrain came and carried off all the cattle in the flocks the Israelites were tending. The sixth plague was a boil breaking forth with blains upon man and upon beast. This was the punishment of the Egyptians, because they would say to the children of Israel, "Go and prepare a bath for us unto the delight of our flesh and our bones." Therefore they were doomed to suffer with boils that inflamed their flesh, and on account of the itch they could not leave off scratching. While the Egyptians suffered thus, the children of Israel used their baths. Because they had sent the Israelites forth into the fields, to plough and sow, hail was sent down upon them, and their trees and crops were destroyed. They had been in the habit of saying to the Israelites, "Go forth, plant ye trees for us, and guard the fruit thereon." Therefore God brought the locusts into the Egyptian border, to eat the residue of that which was escaped, which remained unto them from the hail, for the teeth of the locust are the teeth of a lion, and he hath the jaw teeth of a great lion.
