מַגִּ֤יד מֵֽרֵאשִׁית֙ אַחֲרִ֔ית וּמִקֶּ֖דֶם אֲשֶׁ֣ר לֹא־נַעֲשׂ֑וּ אֹמֵר֙ עֲצָתִ֣י תָק֔וּם וְכָל־חֶפְצִ֖י אֶעֱשֶֽׂה׃
Declaring the end from the beginning, and from ancient times things that are not yet done; Saying: ‘My counsel shall stand, and all My pleasure will I do’;
Rashi on Isaiah
[I] tell the end from the beginning The Egyptian exile and its redemption I announced in the Covenant between the Segments, before they came about.
Ibn Ezra on Isaiah
Declaring the end from the beginning, that is, declaring the event before it happens; for who can annul my decree; my counsel stands for ever, and I will do all my pleasure.
