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." But God's lovingkindness is so great that even in His wrath He has mercy upon the wicked, and as His chief object was not to injure men and beasts, but to damage the vegetation in the fields of the Egyptians, He bade Moses admonish Pharaoh to send and hasten in his cattle and all that he had in the field. But the warning fell on heedless ears. Job was the only one to take it to heart, while Pharaoh and his people regarded not the word of the Lord. Therefore the Lord let the hail smite both man and beast, instead of confining it to the herbs and the trees of the field, as He had intended from the first.
