'Posts' in the Bible

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

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

So the posts that rode upon swift steeds that were used in the king's service went out, being hastened and pressed on by the king's commandment; and the decree was given out in Shushan the palace.
