אֲדֹנָ֤י יְהוִה֙ פָּתַֽח־לִ֣י אֹ֔זֶן וְאָנֹכִ֖י לֹ֣א מָרִ֑יתִי אָח֖וֹר לֹ֥א נְסוּגֹֽתִי׃
El Señor SEÑOR me abrió el oído, y yo no fuí rebelde, ni me torné atrás.
Rashi on Isaiah
opened my ear and let me hear (supra 6:8), “Whom shall I send?” I sent Amos, and they called him ‘pesilus.’ I sent Micah, etc., as is stated in Pesikta of ‘Nachamu nachamu.’
Ibn Ezra on Isaiah
The Lord God hath opened mine ear, etc. Since the Lord hath opened mine ear, and revealed His plan to me, I have not objected to be His messenger.
Rashi on Isaiah
and I did not rebel going on His mission, neither did I turn away backwards, but I said, “Here I am; send me” (ibid.).
