18 For John was saying to Herod, "It is not lawful for you to have your brother's wife."
19 Now Herodias was devising treachery against him; and she wanted to kill him, but she was unable.
20 For Herod was apprehensive of John, knowing him to be a just and holy man, and so he guarded him. And he heard that he was accomplishing many things, and so he listened to him willingly.
21 And when an opportune time had arrived, Herod held a feast on his birthday, with the leaders, and the tribunes, and the first rulers of Galilee.
22 And when the daughter of the same Herodias had entered, and danced, and pleased Herod, along with those who were at table with him, the king said to the girl, "Request from me whatever you want, and I will give it to you."
23 And he swore to her, "Anything that you request, I will give to you, even up to half my kingdom."
24 And when she had gone out, she said to her mother, "What shall I request?" But her mother said, "The head of John the Baptist."
