'Quick' in the Bible

Then the king told Haman, "Quick! Take the clothes and the horse just as you have suggested and do this for Mordecai the Jew who sits in the king's gate. And don't let anything you've suggested fall through the cracks."

The letters were sent in the name of King Ahasuerus and stamped with his ring, and they were taken by men on horseback, going on the quick-running horses used for the king's business, the offspring of his best horses:

So the men went out on the quick-running horses used on the king's business, wasting no time and forced on by the king's order; and the order was given out in Shushan, the king's town.
