Esther 8:10-14

10And 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:

11[stating] that the king granted the Jews that were in every city to gather themselves together, and to stand for their life, to destroy, to slay, and to cause to perish, all the power of the people and province that might assault them, [their] little ones and women, and to [take] the spoil of them for a prey,

12upon one day in all the provinces of king Ahasuerus, upon the thirteenth of the twelfth month, that is, the month Adar.

13That the decree might be given in every province, a copy of the writing was published to all the peoples, and that the Jews should be ready against that day to avenge themselves on their enemies.

14The 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.
