Esther 5:3

Then, as they drank their wine at the feast, the king said to Esther, “What is your petition? For it shall be given to you. And what is your request? Even to half of the kingdom it shall be done.”

And the king said to Esther on the second day also as they drank their wine at the feast, “What is your petition, Queen Esther? It shall be given you. And what is your request? Even to half of the kingdom it shall be done.”

And he swore to her, “Whatever you ask of me, I will give it to you; up to half of my kingdom.”
