יְהוָ֤ה אֱלֹהַי֙ אַתָּ֔ה אֲרֽוֹמִמְךָ֙ אוֹדֶ֣ה שִׁמְךָ֔ כִּ֥י עָשִׂ֖יתָ פֶּ֑לֶא עֵצ֥וֹת מֵֽרָח֖וֹק אֱמ֥וּנָה אֹֽמֶן׃
Herr, mein Gott bist du, ich erhebe dich, ich preise deinen Namen; denn du hast Wunder vollbracht, Beschlüsse aus früher Zeit wurden treu bewahrt.
Rashi on Isaiah
counsels from long ago in true faith Counsels that You advised from long ago to Abraham in the Covenant between the Parts.
Ibn Ezra on Isaiah
My God. The first person singular refers to the prophet, or these are the words which every one of the ancients is represented speaking (24:23).
Rashi on Isaiah
true faith (אֱמוּנָה אֹמֶן). אֹמֶן is like אֹהֶל, tent, אֹכֶל, food, and it is not a verb in present tense but an expression of a noun, obrement (truth) in O.F.
