וּמֹשֶׁ֣ה וְאַהֲרֹ֗ן עָשׂ֛וּ אֶת־כָּל־הַמֹּפְתִ֥ים הָאֵ֖לֶּה לִפְנֵ֣י פַרְעֹ֑ה וַיְחַזֵּ֤ק יְהוָה֙ אֶת־לֵ֣ב פַּרְעֹ֔ה וְלֹֽא־שִׁלַּ֥ח אֶת־בְּנֵֽי־יִשְׂרָאֵ֖ל מֵאַרְצֽוֹ׃ (פ)
Musa dan Harun telah melakukan semua mukjizat ini di hadapan Firaun, tetapi Yang Mahakekal mengeraskan hati Firaun, dan ia tidak membiarkan orang Israel pergi dari negerinya.
Ramban
AND THE ETERNAL SAID UNTO MOSES: PHARAOH WILL NOT HEARKEN UNTO YOU. It was to be expected that Pharaoh and his servants should dread the plague of the firstborn and be in consternation thereof moreso than for anything that had happened to them — indeed they had previously seen all the words of Moses fulfilled. G-d therefore informed Moses that it is He Who is hardening his [Pharaoh’s] heart, so that His wonders would be multiplied through the plague of the firstborn in both man and beast and the judgments He will execute against their gods.94Further, 12:12.
Rashi commented: “So that My wonders may be multiplied. This refers to the slaying of the firstborn, the division of the Red Sea, and the overthrowing of the Egyptians in it.” This explanation is not possible, because of the verse after that which states, And the Eternal hardened Pharaoh’s heart, and he did not let the children of Israel go out of his land.96Verse 10. This indicates that the expression, that My wonders may be multiplied, which was mentioned in Verse 9, refers only to those wonders which took place before the exodus, as Verse 10 clearly indicates that on account of the hardening of Pharaoh’s heart he did not let the people go. It thus cannot refer to the division of the Red Sea and the overthrowing of the Egyptians in it, as these wonders happened after the exodus (Mizrachi).

Who would grant! Scripture does not say, “who would grant me ”, but rather, “who would grant them ” (the word them is displaced in the sentence, and appears after that they had such a will). Know that the Divine decree underlies all actions and all phenomena, in the sense that the nature and potentiality of everything in the universe, including living creatures, is determined by the action of the constellations on the four elements. A creature’s behavior at every moment is governed by its nature and its potential. However, as the author of the Sefer Yeṣira has explained, a certain amount of deviation can exist. Individuals derive their nature from the species, and they can change their nature within the boundaries of their species’s potential. This is the meaning of “God hardened the heart of Pharaoh” [Exodus 9: 12], although elsewhere Scripture asserts, “he hardened his heart; he and his officials” [Exodus 9: 34]. Both statements are true. Accordingly the prophets have said, “I know, God , that the way of a man is not in himself” [Jeremiah 10: 23] and “Why have you made us stray, God , from Your ways?” [Isaiah 63: 17]. Nevertheless, Moshe said, “choose life” [30: 19]. God does not prevent anyone from achieving good. Indeed, He wishes to bestow good; and Scripture says so anthropomorphically by using the expression, Who would grant.
