They are created now, and not from of old. Before today, you didn’t hear them, lest you should say, ‘Behold, I knew them.’ Yes, you didn’t hear. Yes, you didn’t know. Yes, from of old your ear was not opened, for I knew that you dealt very treacherously, and were called a transgressor from the womb. For my name’s sake, I will defer my anger, and for my praise, I hold it back for you so that I don’t cut you off. Behold, I have refined you, but not as silver. I have chosen you in the furnace of affliction. For my own sake, for my own sake, I will do it; for how would my name be profaned? I will not give my glory to another.
