All Egypt trembled before the awful outpouring of divine judgment. Pharaoh hastily sent for the two brothers, and cried out, “I have sinned this time: the Lord is righteous, and I and my people are wicked. Entreat the Lord (for it is enough) that there be no more mighty thunderings and hail; and I will let you go, and ye shall stay no longer.” Exodus 9:27, 28. The answer was, “As soon as I am gone out of the city, I will spread abroad my hands unto the Lord; and the thunder shall cease, neither shall there be any more hail; that thou mayest know how that the earth is the Lord’s. But as for thee and thy servants, I know that ye will not yet fear the Lord God.” Exodus 9:29, 30. (PP 270.1) MC VC

Moses knew that the contest was not ended. Pharaoh’s confessions and promises were not the effect of any radical change in his mind or heart, but were wrung from him by terror and anguish. Moses promised, however, to grant his request; for he would give him no occasion for further stubbornness. The prophet went forth, unheeding the fury of the tempest, and Pharaoh and all his host were witnesses to the power of Jehovah to preserve His messenger. Having passed without the city, Moses “spread abroad his hands unto the Lord: and the thunders and hail ceased, and the rain was not poured upon the earth.” Exodus 9:33. But no sooner had the king recovered from his fears than his heart returned to its perversity. (PP 270.2) MC VC

Then the Lord said unto Moses, “Go in unto Pharaoh: for I have hardened his heart, and the heart of his servants, that I might show these My signs before him; and that thou mayest tell in the ears of thy son, and of thy son’s son, what things I have wrought in Egypt, and My signs which I have done among them; that ye may know how that I am Jehovah.” Exodus 10:1, 2. The Lord was manifesting His power, to confirm the faith of Israel in Him as the only true and living God. He would give unmistakable evidence of the difference He placed between them and the Egyptians, and would cause all nations to know that the Hebrews, whom they had despised and oppressed, were under the protection of the God of heaven.

Moses warned the monarch that if he still remained obstinate, a plague of locusts would be sent, which would cover the face of the earth and eat up every green thing that remained; they would fill the houses, even the palace itself; such a scourge, he said, as “neither thy fathers, nor thy fathers’ fathers have seen, since the day that they were upon the earth unto this day.” Exodus 10:6.
