Mark 6:22-25

22Now [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.”

23And he swore to her, “Whatever you ask me, I will give it to you; up to half of my kingdom.”

24She went out and said to her mother, “What shall I ask for?” And Herodias replied, “The head of John the Baptist!”

25And she rushed back to the king and asked, saying, “I want you to give me right now the head of John the Baptist on a platter!”
