וַאֲנִ֗י זֹ֣את בְּרִיתִ֤י אוֹתָם֙ אָמַ֣ר יְהוָ֔ה רוּחִי֙ אֲשֶׁ֣ר עָלֶ֔יךָ וּדְבָרַ֖י אֲשֶׁר־שַׂ֣מְתִּי בְּפִ֑יךָ לֹֽא־יָמ֡וּשׁוּ מִפִּיךָ֩ וּמִפִּ֨י זַרְעֲךָ֜ וּמִפִּ֨י זֶ֤רַע זַרְעֲךָ֙ אָמַ֣ר יְהוָ֔ה מֵעַתָּ֖ה וְעַד־עוֹלָֽם׃ (ס)
「至於我，我與他們所立的約乃是這樣，」永恆者說：「我加在你身上的靈，和我放在你口中的話，必不離開你的口，也不離開你後裔的口，也不離開你後裔之後裔的口，從今時直到永遠。」這是永恆者說的。
Rashi
As for Me, this is My covenant with them In this matter, I made a covenant with them, and I will fulfill it, for even in their exile, My Torah shall not be forgotten from them.
Ibn Ezra
As for me, this is my covenant. I shall make a covenant with them, namely, that my spirit which is upon thee, etc. Upon thee. Israel is addressed. My spirit. My prophecy; comp. And it shall come to pass afterward, that I will pour out my spirit upon all flesh, etc. (Joel 3:1).
Metzudat David
"And for me, this is my covenant:" He means to say, "Upon this I will make a covenant with them, 'says the Lord.'" And [then] he explained what he made the covenant upon and said, "The spirit of prophecy that rests upon you - you, Israel - and the words of Torah that I placed in your mouth to teach them, behold these two 'will not depart from your mouth, etc. says the Lord,' such that they will not depart 'from now and forever' until the end of all the generations."
