Mark 6:22-25

22Then his daughter, also named Herodias, came in and performed a dance that greatly pleased Herod and his guests. “Ask me for anything you like,” the king said to the girl, “and I will give it to you.”

23He even vowed, “I will give you whatever you ask, up to half my kingdom!”

24She went out and asked her mother, “What should I ask for?” Her mother told her, “Ask for the head of John the Baptist!”

25So the girl hurried back to the king and told him, “I want the head of John the Baptist, right now, on a tray!”
