'Runners' in the Bible

and letters to be sent by the hand of the runners unto all provinces of the king, to cut off, to slay, and to destroy all the Jews, from young even unto old, infant and women, on one day, on the thirteenth of the twelfth month -- it is the month of Adar -- and their spoil to seize,

The runners have gone forth, hastened by the word of the king, and the law hath been given in Shushan the palace, and the king and Haman have sat down to drink, and the city Shushan is perplexed.

And he writeth in the name of the king Ahasuerus, and sealeth with the signet of the king, and sendeth letters by the hand of the runners with horses, riders of the dromedary, the mules, the young mares,

The runners, riding on the dromedary, and the mules, have gone out, hastened and pressed by the word of the king, and the law hath been given in Shushan the palace.
