'Half' in the Bible

The king asked her, "What do you want, Queen Esther? What is your request? Even if it's half of the kingdom, it will be given to you."

While they were drinking wine, the king asked Esther, "What's your petition? It will be given to you. What's your request? Up to half of the kingdom, and it will be done."

On the second day the king again told Esther as they drank wine, "What's your petition, Queen Esther? It will be given to you. What's your request? Up to half of the kingdom, and it will be done."
