וְנָגַ֧ף יְהוָ֛ה אֶת־מִצְרַ֖יִם נָגֹ֣ף וְרָפ֑וֹא וְשָׁ֙בוּ֙ עַד־יְהוָ֔ה וְנֶעְתַּ֥ר לָהֶ֖ם וּרְפָאָֽם׃
永恆者必擊打埃及，先擊打，後醫治；他們必歸向永恆者，祂必應允他們的祈求，醫治他們。
Rashi
And a time to heal. Their ruin, as the matter is stated concerning Egypt, “and they will repent to Adonoy, and He will accept their prayer and heal them.”4Yeshayahu 19:22.
