Mark 6:19-24

19So Herodias held a grudge against John and wanted to kill him. But she had been unable, 20because Herod feared John and protected him, knowing that he was a righteous and holy man. When he heard John’s words, he was greatly perplexed; yet he listened to him gladly.

21On Herod’s birthday, her opportunity arose. Herod held a banquet for his nobles and military commanders and the leading men of Galilee. 22When the daughter of Herodias1 came and danced, she pleased Herod and his guests, and the king said to the girl, “Ask me for whatever you wish, and I will give it to you.” 23And he swore to her, “Whatever you ask of me, I will give you, up to half my kingdom!”

24Then she went out and asked her mother, “What should I request?”

And her mother answered, “The head of John the Baptist.”
