Mark 6:23-26
6:23 He swore to her, “Whatever you ask I will give you, up to half my kingdom.”
6:24 So she went out and said to her mother, “What should I ask for?” Her mother said, “The head of John the baptizer.”
6:25 Immediately she hurried back to the king and made her request: “I want the head of John the Baptist on a platter immediately.”
6:26 Although it grieved the king deeply, he did not want to reject her request because of his oath and his guests.
