For I knew that you are stubborn, and that your neck is like an iron sinew, and that your forehead is like brass.
Because I knew that thou art obstinate, and thy neck is an iron sinew, and thy brow brass;
Because I knew that you were obstinate, and your neck was an iron sinew and your brow was brass,
Because I know that you are stubborn, your neck is made of iron, and your forehead is bronze.
