אֲדֹנָ֤י יְהוִה֙ פָּתַֽח־לִ֣י אֹ֔זֶן וְאָנֹכִ֖י לֹ֣א מָרִ֑יתִי אָח֖וֹר לֹ֥א נְסוּגֹֽתִי׃
Gott, der Herr, hat mir das Ohr geöffnet, und ich sträubte mich nicht, [auf seine Worte zu hören], ich bin nicht zurückgewichen [von seinem Befehl].

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.

and I did not rebel going on His mission, neither did I turn away backwards, but I said, “Here I am; send me” (ibid.).
