At ibibigay Ko ang mga Egipcio sa kamay ng isang malupit na panginoon, at isang mabagsik na hari ang maghahari sa kanila, sabi ng Panginoon, ang Walang-Hanggan ng mga Hukbo.
Rashi
And I will deliver וְסִכַּרְתִּי, And I will deliver. Alternatively, it can be interpreted as an expression like (Gen. 8:2): “And the fountains of the deep were stopped up (וַיִּסָּכְרוּ).” I will stop him up and bind him.
Ibn Ezra
וסכרתי And I will give over. The כ is here, according to some, substituted for נ, but, in fact, only the silent letters interchange; it is rather to be compared with ויסכרו and were stopped2The second explanation is not different from the first in substance, but in the wording, because after all סכר means the same as סגר to shut, to stop, to deliver up, whether we say that the former is derived from the latter by the change of ג into כ or not. (Gen. 8:2).
Rashi
into the hands of a harsh master Heb. אֲדֹנִים קָשֶׁה. Any expression of lordship is used in the plural, even for a singular. Comp. (ibid. 39:20) “Joseph’s master (אֲדֹנֵי)”; (ibid. 16) “Until his master (אֲדֹנָיו) came.”
