Isaiah 50:4-7

The Lord GOD has given me the tongue of those who are taught, that I may know how to sustain with a word him who is weary. Morning by morning he awakens; he awakens my ear to hear as those who are taught. The Lord GOD has opened my ear, and I was not rebellious; I turned not backward. I gave my back to those who strike, and my cheeks to those who pull out the beard; I hid not my face from disgrace and spitting. But the Lord GOD helps me; therefore I have not been disgraced; therefore I have set my face like a flint, and I know that I shall not be put to shame.
