Mark 6:21-23

But an opportune time [finally] came [for Herodias]. Herod on his birthday gave a banquet for his officials (nobles, courtiers) and military commanders and the leading men of Galilee. Now [Salome] the daughter of Herodias came in and danced [for the men]. She pleased and beguiled Herod and his dinner guests; and the king said to the girl, “Ask me for whatever you want and I will give it to you.” And he swore to her, “Whatever you ask me, I will give it to you; up to half of my kingdom.” [Esth 5:3, 6]
