Tafsiran Keluaran 14:8: Rashi, Chizkuni, Sforno & Or HaChaim

וַיְחַזֵּ֣ק יְהֹוָ֗ה אֶת־לֵ֤ב פַּרְעֹה֙ מֶ֣לֶךְ מִצְרַ֔יִם וַיִּרְדֹּ֕ף אַחֲרֵ֖י בְּנֵ֣י יִשְׂרָאֵ֑ל וּבְנֵ֣י יִשְׂרָאֵ֔ל יֹצְאִ֖ים בְּיָ֥ד רָמָֽה׃

Yang Mahakekal mengeraskan hati Firaun, raja Mesir, sehingga ia mengejar orang Israel, sementara orang Israel sedang keluar dengan tangan yang terangkat.

Rashi

ויחזק ה׳ את לב פרעה AND THE LORD ALLOWED THE HEART OF PHARAOH TO BE HARDENED — the meaning is, that he was in doubt whether to pursue or not, and He hardened his heart to pursue (Mekhilta).

Chizkuni

ביד רמה, “fully confident;” they thought that they had nothing to fear as they had left Egypt with permission.

Sforno

ובני ישראל יוצאים ביד רמה, the meaning of the word רמה here is similar to the meaning of the same word in Deuteronomy 32,27 ידינו רמה, where it means: “our own hand has prevailed.” At the time of their departure they had been confident of their ability to defeat Pharaoh and his military machine as they were much stronger in numbers. The verse teaches that they were relying on their numbers instead of considering their total lack of experience in the art of war. They would have had every reason to fear the numerically inferior Egyptians who had all this experience going for them.
