Now you may write in the king’s name as you please regarding the Jews, and seal it with the royal signet ring. For a decree that is written in the name of the king and sealed with the royal signet ring cannot be revoked.”
Jewish Publication Society of America Version (JPS1917) - Esther 8:8 >Write ye also concerning the Jews, as it liketh you, in the king's name, and seal it with the king's ring; for the writing which is written in the king's name, and sealed with the king's ring, may no man reverse.'
