Mark 6:19

17For Herod himself had sent out and arrested John and bound him in prison for the sake of Herodias, his brother Philip’s wife, for he had married her.

18For John had said to Herod, “It is not lawful for you to have your brother’s wife.”

19Herodias set herself against him and desired to kill him, but she couldn’t,

20for Herod feared John, knowing that he was a righteous and holy man, and kept him safe. When he heard him, he did many things, and he heard him gladly.

21Then a convenient day came when Herod on his birthday made a supper for his nobles, the high officers, and the chief men of Galilee.
