כֹּֽה־אָמַ֨ר יְהוָ֧ה מֶֽלֶךְ־יִשְׂרָאֵ֛ל וְגֹאֲל֖וֹ יְהוָ֣ה צְבָא֑וֹת אֲנִ֤י רִאשׁוֹן֙ וַאֲנִ֣י אַחֲר֔וֹן וּמִבַּלְעָדַ֖י אֵ֥ין אֱלֹהִֽים׃
Also spricht der Herr, der König Israels und sein Erlöser, der Herr Zebaot: Ich bin der Erste und ich bin der Letzte, außer mir gibt es keinen Gott.
Ibn Ezra on Isaiah
The King of Israel, When the Israelites were in their own land. And his redeemer, when he is in exile.
Ibn Ezra on Isaiah
The Lord of hosts. He is always king, and the hosts of heaven testify it.
Ibn Ezra on Isaiah
I am the first, the first king.6I. E. explains ראשון by מלך ראשון the first king, because the context demands here rather the declaration that God is the King and Ruler of the universe, that every thing that happens is caused and commanded by Him, than a description of His Eternity.
