Isaiah 50:3-6

I dress the sky with darkness and shroud it with sackcloth.” The Lord YAHWEH has equipped me with the anointed, skillful tongue of a teacher — to know how to speak a timely word to the weary. Morning by morning, he awakens my heart. He opens my ears to hear his voice, to be trained to teach. The Lord YAHWEH has opened my ear, and I did not resist; I did not rebel. I offered my back to those who flogged me and my cheek to those who tore out my beard. I never hid my face from demeaning insults or from those who spit on me.
