Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as hath not been seen (Exod. 9:18). Zabdi the son of Levi said: He made a mark upon the wall and told him that when the sun reached that mark tomorrow, the hail would fall. Such as hath not been seen implies that it would be a hail like none that had occurred previously, and would occur again only in the days to come, that is, in the time of Gog and Magog, as it is said: Which I have reserved against the time of trouble, against the day of battle and war (Job 38:23). It also says: And I will plead against him with pestilence and with blood; an overflowing shower and great hailstones (Exod. 38:22). And now therefore send, hasten in thy cattle (ibid. 9:19), on account of the plague of hail. He said to him: Wicked one, the Lord is righteous indeed.
And Moses stretched forth his rod unto heaven, and the Lord sent thunder and hail (ibid., v. 23). Wherever Scripture says and the Lord it refers to Him and to His heavenly court. And the Lord did unto Sarah as he had spoken (Gen. 21:1), that is, He and His court. And the Lord caused it to rain on Sodom (ibid. 20:24), that is, He and His court. And the Lord sent thunder and hail (Exod. 9:23), that is, He and His court. So there was hail, and fire flashing up amidst the hail (ibid., v. 24). The words fire flashing indicate that after the hail, the fire flashed and consumed it, as is said: But the wheat and the spelt were not smitten, for they ripen late (ibid., v. 32). R. Phinehas and R. Judah the son of Shalum discussed this matter. R. Phinehas said: What is the meaning of ripen late? It indicates that the Holy One, blessed Be, performed a miracle with them. R. Judah, however, insisted that they were merely late in ripening. R. Phinehas maintained: It is written: And the hail smote every herb of the field (ibid., v. 25), and yet you insist that they were not smitten because they were still young. Obviously that is not so. The Holy One, blessed be He, performed a miracle with them.
At that very moment the wicked Pharaoh cried out: Entreat the Lord … and I will let them go (Exod. 9:28). Moses replied: You said that at the time of the first plague, and I pleaded in your behalf, but yet you did not send them away. Why should I entreat for thee and for thy servants? (ibid. 8:5). Pharaoh replied: I have sinned before the Lord your God and against you, but now I will let them go. When Moses heard that, Moses went out of the city from Pharaoh, and spread forth his hands unto the Lord; and the thunders and the hail ceased, and the rain was not poured upon the earth (ibid. 9:33). They were suspended in mid-air. When did they descend? Some descended upon the Amorites in the days of Joshua, as it is said: The Lord cast down great stones from heaven upon them (Josh. 10:11), and the remainder will fall on Gog and Magog in the days of the Messiah. And the thunders ceased (Exod. 9:34). They, too, were suspended (in mid-air). They descended in the days of Elisha, against the camp of the Arameans, as it is said: For the Lord had made the hosts of the Arameans, to hear a noise of chariots, and a noise of horses (II Kings 7:6).
