'Half' in the Bible

Then the king asked her, "What would you like, queen Esther? What is your request? It shall be given you even to the half of the kingdom."

The king said to Esther at the banquet of wine, "What is your petition? It shall be granted you. What is your request? Even to the half of the kingdom it shall be performed."

The king said again to Esther on the second day at the banquet of wine, "What is your petition, queen Esther? It shall be granted you. What is your request? Even to the half of the kingdom it shall be performed."
