'Half' in the Bible

And the king said to her, What wilt thou, queen Esther? and what is thy request? it shall be given thee even to the half of the kingdom.

And the king said to Esther at the banquet of wine, What is thy petition? and it shall be granted thee; and what is thy request? even to the half of the kingdom it shall be done.

And the king said again to Esther on the second day, at the banquet of wine, What is thy petition, queen Esther? and it shall be granted thee; and what is thy request? even to the half of the kingdom it shall be done.
