'Five' in the Bible

And in Shushan the fortress the Jews slew and destroyed five hundred men.

And the king said to Esther the queen, The Jews have slain and destroyed five hundred men in Shushan the fortress, and the ten sons of Haman; what have they done in the rest of the king's provinces? And what is thy petition? and it shall be granted thee; and what is thy request further? and it shall be done.
