'Couriers' in the Bible

And the letters were sent by couriers into all the king's provinces, to destroy, to kill, and to cause to perish, all Jews, both young and old, little children and women, in one day, upon the thirteenth of the twelfth month, that is, the month Adar, and to take the spoil of them for a prey.

The couriers went out, being hastened by the king's commandment, and the decree was given in Shushan the fortress. And the king and Haman sat down to drink; but the city of Shushan was in consternation.

And he wrote in the name of king Ahasuerus, and sealed it with the king's ring, and sent letters by couriers on horseback riding on coursers, horses of blood reared in the breeding studs:

The couriers mounted on coursers and horses of blood went out, being hastened and pressed on by the king's commandment. And the decree was given at Shushan the fortress.
