'Concerning' in the Bible

All the king’s servants who were at the king’s gate [in royal service] bowed down and honored and paid homage to Haman; for this is what the king had commanded in regard to him. But Mordecai [a Jew of the tribe of Benjamin] neither bowed down nor paid homage [to him].

Also, concerning the Jews, write as you see fit, in the king’s name, and seal it with the king’s signet ring—for a decree which is written in the king’s name and sealed with the king’s signet ring may not be revoked.”
