Mark 6:17-20

17 For Herod himself had sent and laid hold of John, and bound him in prison for the sake of Herodias, his brother Philip's wife; for he had married her.
18 For John had said to Herod, "It is not lawful for you to have your brother's wife."
19 Therefore Herodias held it against him and wanted to kill him, but she could not;
20 for Herod feared John, knowing that he was a just and holy man, and he protected him. And when he heard him, he did many things, and heard him gladly.
