Patristic
c. A.D. 347–420
“(Verse 22.) And the Lord will strike Egypt with a plague, and He will heal it. And they will turn to the Lord, and He will be appeased by them, and He will heal them. For whom the Lord loves, He chastises, and He punishes every son whom He receives. Persecution does not pertain to the denial of believers, but to their testing and reward.”
