Herod was the one who had John arrested and bound in prison on account of Herodias, the wife of his brother Philip, whom he had married. John had said to Herod, “It is not lawful for you to have your brother’s wife.” Herodias harbored a grudge against him and wanted to kill him but was unable to do so. Herod feared John, knowing him to be a righteous and holy man, and kept him in custody. When he heard him speak he was very much perplexed, yet he liked to listen to him. Mark 6, 17-20
