But now, do not consider him innocent. You are a man of wisdom; you will know what to do to him. Bring his gray head down to the grave in blood."Catholic Public Domain Version
yet do not choose to treat him as if he were innocent. Since you are a wise man, you will know what to do with him. And you shall lead away his grey hair to death with blood.
