Isaiah 48:4

Because I know that you are obstinate,

and your neck is an iron sinew

and your forehead brass,

For I knew how stubborn you were;

your neck muscles were iron,

your forehead was bronze.

For I know how stubborn and obstinate you are.

Your necks are as unbending as iron.

Your heads are as hard as bronze.

because I know that you are obstinate,

and your neck an iron sinew,

and your forehead bronze.

Because I knew that thou art obstinate,

And thy neck is an iron sinew,

And thy brow brass;
