וּבְכָ֥ה וּֽבְעַמְּךָ֖ וּבְכָל־עֲבָדֶ֑יךָ יַעֲל֖וּ הַֽצְפַרְדְּעִֽים׃
אי אױף דיר, אי אױף דײַן פֿאָלק, אי אױף אַלע דײַנע קנעכט, װעלן אַרױפֿגײן די פרעש.
Tze'enah Ure'enah
“The frogs shall come up on you” [7:29]. The frogs came into the bowels of the people and croaked inside their bodies.22Rashi, Exodus, 7:29.
Rashi
ובכה ובעמך AND UPON (or in) THEE AND THY PEOPLE [SHALL THE FROGS COME] — they made their way right into their bodies and crowed (Exodus Rabbah 10:3).
Chizkuni
ובכה ובעמך, “and against you as well as against your people, etc;” the word: ובכה is to be read as if it had been spelled as ובך.
