Though the Egyptians had so long rejected the knowledge of God, the Lord still gave them opportunity for repentance. In the days of Joseph, Egypt had been an asylum for Israel; God had been honored in the kindness shown His people; and now the long-suffering One, slow to anger, and full of compassion, gave each judgment time to do its work; the Egyptians, cursed through the very objects they had worshiped, had evidence of the power of Jehovah, and all who would, might submit to God and escape His judgments. The bigotry and stubbornness of the king resulted in spreading the knowledge of God, and bringing many of the Egyptians to give themselves to His service.

Skønt ægypterne så længe havde forkastet kundskaben om Gud, gav Herren dem endnu en mulighed for omvendelse. På Josefs tid havde Ægypten været et fristed for Israel. Gud var blevet æret ved den venlighed, der var blevet vist over for hans folk, og nu gav han, som er langmodig, sen til vrede og fuld af medlidenhed, hver enkelt plage tid til at gøre sin virkning. Forbandelsen ramte ægypterne netop på de ting, de havde tilbedt. De fik beviser for Guds magt, og alle de der ville, kunne bøje sig for Gud og derved undgå hans straf. Kongens stædighed og forblindelse resulterede i, at kundskaben om Gud udbredtes, og at mange ægyptere begyndte at tjene Gud.
