Context
21 Then a convenient day came when Herod on his birthday made a supper for his nobles, the high officers, and the chief men of Galilee.
22 When the daughter of Herodias herself came in and danced, she pleased Herod and those sitting with him. The king said to the young lady, “Ask me whatever you want, and I will give it to you.”
23 He swore to her, “Whatever you ask of me, I will give you, up to half of my kingdom.”
