'Couriers' in the Bible

So the couriers went with the letters from the king and his princes throughout all Israel and Judah, and according to the commandment of the king, saying, "You children of Israel, turn again to Yahweh, the God of Abraham, Isaac, and Israel, that he may return to the remnant that have escaped of you out of the hand of the kings of Assyria.

So the couriers passed from city to city through the country of Ephraim and Manasseh, even to Zebulun: but they ridiculed them, and mocked them.

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, even on the thirteenth day of the twelfth month, which is the month Adar, and to plunder their possessions.

The couriers went forth in haste by the king's commandment, and the decree was given out in the citadel of Susa. The king and Haman sat down to drink; but the city of Shushan was perplexed.

So the couriers who rode on royal horses went out, hastened and pressed on by the king's commandment. The decree was given out in the citadel of Susa.
