Mark 6:17-20

17For Herod himself had sent men and had John arrested and bound in prison on account of 1Herodias, the wife of his brother Philip, because he had married her.

18For John had been saying to Herod, “2It is not lawful for you to have your brother’s wife.”

19And 3Herodias held a grudge against him and wanted to put him to death, and could not do so;

20for 4Herod was afraid of John, knowing that he was a righteous and holy man, and he had been protecting him. And when he heard him, he was very perplexed; and yet he 5used to enjoy listening to him.
