ישעיהו יב:ב פירוש: רש״י ואבן עזרא

for the strength and the praise of the Eternal the Lord The strength and the praise of the Holy One, blessed be He, that was my salvation. We cannot, however, explain עָזִּי, like עֻזִּי, my strength, for we do not find in Scripture עָזִּי vowelized with a short ‘kamatz,’ but with a ‘shuruk,’ reading עֻזִּי, with the exception of three places where it is accompanied by וְזִמְרָת. Also, וְזִמְרָת cannot be explained like וְזִמְרָתִי, my praise, but we are forced to say that וְזִמְרָת is connected to the word following it. Therefore, I say that the ‘yud’ of עָזִּי is merely like the ‘yud’ of (Deut. 33:16) שׁוֹכְנִי סְנֶה, “He Who dwells in the thornbush.”

הנה אל ישועתי The God of my salvation is with me,¹A. V. God is my salvation. and therefore אבטח I will dwell in safety.²A. V. I trust.

the Eternal the Lord Until now His Name was divided, and with the downfall of Amalek, it became whole, and so Scripture states (Exodus 17:16): “For the hand is on the throne of the Eternal (כֵּס יָהּ),” implying that the throne is incomplete and the Name is incomplete until the Lord wages war against Amalek.
