Esther 5:6

5:6 While at the banquet of wine, the king said to Esther, “What is your request? It shall be given to you. What is your petition? Ask for as much as half the kingdom, ¹  and it shall be done!”

Esther 7:2

7:2 On the second day of the banquet of wine the king asked Esther, “What is your request, Queen Esther? It shall be granted to you. And what is your petition? Ask up to half the kingdom, and it shall be done!”

Esther 9:12

9:12 Then the king said to Queen Esther, “In Susa the citadel the Jews have killed and destroyed five hundred men and the ten sons of Haman! What then have they done in the rest of the king’s provinces? What is your request? It shall be given to you. What other petition do you have? It shall be done.”

¹ sn As much as half the kingdom. Such a statement would no doubt have been understood for the exaggeration that it clearly was. Cf. the similar NT scene recorded in Mark 6:23, where Herod makes a similar promise to the daughter of Herodias. In that case the request was for the head of John the Baptist, which is a lot less than half the kingdom.
