וַאדֹנָ֤י יְהוִה֙ יַֽעֲזָר־לִ֔י עַל־כֵּ֖ן לֹ֣א נִכְלָ֑מְתִּי עַל־כֵּ֞ן שַׂ֤מְתִּי פָנַי֙ כַּֽחַלָּמִ֔ישׁ וָאֵדַ֖ע כִּי־לֹ֥א אֵבֽוֹשׁ׃
Targum Jonathan on Isaiah
The Lord God is my helper, therefore shall I not be confounded : therefore have I set my face strong as a rock, and I know that I shall not be confounded.
