Exodus 9:18 Behold, to morrow about this time I will cause it to rain a very grievous hail, such as hath not been in Egypt since the foundation thereof even until now.
[Patriarchs & Prophets pp 269] 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.” 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. 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.” 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.
Exodus 9:25 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. 26 Only in the land of Goshen, where the children of Israel were, was there no hail.
May God add His blessing to the study of His word. “Good night” and God bless!
