Those who are quieting a guilty conscience with the thought that they can change a course of evil when they choose, that they can trifle with the invitations of mercy, and yet be again and again impressed, take this course at their peril. They think that after casting all their influence on the side of the great rebel, in a moment of utmost extremity, when danger compasses them about, they will change leaders. But this is not so easily done. The experience, the education, the discipline of a life of sinful indulgence, has so thoroughly molded the character that they cannot then receive the image of Jesus. Had no light shone upon their pathway, the case would have been different. Mercy might interpose, and give them an opportunity to accept her overtures; but after light has been long rejected and despised, it will be finally withdrawn. (PP 269.1) MC VC

A plague of hail was next threatened upon Pharaoh, with the warning, “Send therefore now, and gather thy cattle, and all that thou hast in the field; for upon every man and beast which shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die.” Exodus 9:19. Rain or hail was unusual in Egypt, and such a storm as was foretold had never been witnessed. The report spread rapidly, and all who believed the word of the Lord gathered in their cattle, while those who despised the warning left them in the field. Thus in the midst of judgment the mercy of God was displayed, the people were tested, and it was shown how many had been led to fear God by the manifestation of His power. (PP 269.2) MC VC

The storm came as predicted—thunder and hail, and fire mingled with it, “very grievous, such as there was none like it in all the land of Egypt since it became a nation. And the hail smote throughout all the land of Egypt all that was in the field, both man and beast; and the hail smote every herb of the field, and brake every tree of the field.” Exodus 9:24, 25. Ruin and desolation marked the path of the destroying angel. The land of Goshen alone was spared. It was demonstrated to the Egyptians that the earth is under the control of the living God, that the elements obey His voice, and that the only safety is in obedience to Him. (PP 269.3) MC VC

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. (PP 270.4) MC VC
