לְמַכֵּ֣ה מִ֭צְרַיִם בִּבְכוֹרֵיהֶ֑ם כִּ֖י לְעוֹלָ֣ם חַסְדּֽוֹ׃
Sa Kanya na humampas sa Egipto sa kanilang mga panganay, sapagkat magpakailanman ang Kanyang kagandahang-loob.
Rashi
To Him Who smote the Egyptians with their firstborn It does not say, “their firstborn,” but “with their firstborn.” The firstborn arose and beat their fathers’ legs because they detained Israel, when they heard about the tenth plague from Moses.
