The fourth plague was also announced to the king early in the morning by the river's brink. Pharaoh went thither regularly, for he was one of the magi, who need water for their enchantments.[186] Moses' daily morning visits were beginning to annoy him, and he left the house early, in the hope of circumventing his monitor. But God, who knows the thoughts of man, sent Moses to Pharaoh at the very moment of his going forth.

The warning of the plague that was imminent not having had any effect upon Pharaoh, God sent the fourth plague upon Egypt,[187] a mixed horde of wild animals, lions, bears, wolves, and panthers, and so many birds of prey of different kinds that the light of the sun and the moon was darkened as they circled through the air. These beasts came upon the Egyptians as a punishment for desiring to force the seed of Abraham to amalgamate with the other nations. God retaliated by bringing a mixture upon them that cost them their life.[188]

As Pharaoh had been the first of the Egyptians to lay evil plans against the children of Israel, so he was the first upon whom descended punishment. Into his house the mixed horde of beasts came first of all, and then into the houses of the rest of the Egyptians. Goshen, the land inhabited by the Israelites, was spared entirely, for God put a division between the two peoples. It is true, the Israelites had committed sins enough to deserve punishment, but the Holy One, blessed be He, permitted the Egyptians to act as a ransom for Israel.

Again Pharaoh expressed his willingness to let the children of Israel sacrifice unto their God, but they were to stay in the land and do it, not go outside, into the wilderness. Moses pointed out to Pharaoh how unbecoming it would be for the Israelites to sacrifice, before the very eyes of his people, the animals that the Egyptians worshipped as gods. Then Pharaoh consented to let them go beyond the borders of his land, only they were not to go very far away, and Moses, to mislead him, asked for a three days' journey into the wilderness. But, again, when Moses had entreated God on Pharaoh's behalf, and the horde of wild beasts had vanished, the king hardened his heart, and did not let the people go.

The cessation of the fourth plague was as miraculous as the plague itself. The very animals that had been slain by the Egyptians in self-defense returned to life and departed from the land with the rest. This was ordained to prevent the wicked oppressors from profiting by the punishment even so much as the value of the hides and the flesh of the dead animals. It had not been so with the useless frogs, they had died on the spot, and their carcasses had remained where they fell.[189]

The fifth plague inflicted by God upon the Egyptians was a grievous pestilence, which mowed down the cattle and beasts chiefly, yet it did not spare men altogether. This pestilence was a distinct plague, but it also accompanied all the other plagues, and the death of many Egyptians was due to it.[190] The Israelites again came off unscathed. Indeed, if an Israelite had a just claim upon a beast held by an Egyptian, it, too, was spared, and the same good fortune waited upon such cattle as was the common property of Israelites and Egyptians.

The sixth plague, the plague of boils, was produced by Moses and Aaron together in a miraculous way. Each took a handful of ashes of the furnace, then Moses held the contents of the two heaps in the hollow of one of his hands, and sprinkled the ashes tip toward the heaven, and it flew so high that it reached the Divine throne. Returning earthward, it scattered over the whole land of Egypt, a space equal to four hundred square parasangs. The small dust of the ashes produced leprosy upon the skin of the Egyptians,[191] and blains of a peculiar kind, soft within and dry on top.[192]

The first five plagues the magicians had tried to imitate, and partly they had succeeded. But in this sixth plague they could not stand before Moses, and thenceforth they gave up the attempt to do as he did. Their craft had all along been harmful to themselves. Although they could produce the plagues, they could not imitate Moses in causing them to disappear. They would put their hands into their bosom, and draw them out white with leprosy, exactly like Moses, but their flesh remained leprous until the day of their death. And the same happened with all the other plagues that they imitated: until their dying day they were afflicted with the ills they produced.[193]

As Pharaoh had wittingly hardened his heart with each of the first five plagues, and refused to turn from his sinful purpose, God punished him thereafter in such wise that he could not mend his ways if he would. God said, "Even though he should desire to do penance now, I will harden his heart until he pays off the whole of his debt."

Pharaoh had observed that whenever he walked on the brink of the Nile, Moses would intercept him. He therefore gave up his morning walk. But God bade Moses seek the king in his palace in the early hours of the day and urge him to repent of his evil ways. Therefore Moses spake to him as follows, in the name of God: "O thou villain! Thou thinkest that I cannot destroy thee from the world. Consider, if I had desired it, instead of smiting the cattle, I might have smitten thee and thy people with the pestilence, and thou wouldst have been cut off from the earth. I inflicted the plague only in such degree as was necessary to show thee My power, and that My Name may be declared throughout all the earth. But thou dost not leave off treading My people underfoot. Behold, to-morrow when the sun passes this point,"—whereat Moses made a stroke upon the wall— "I will cause a very grievous hail to pour down, such as will be only once more, when I annihilate Gog with hail, fire, and brimstone."
