Mark 6:16-18

16But when Herod heard thereof, he said, It is John, whom I beheaded: he is risen from the dead.

17For Herod himself had sent forth and laid hold upon John, and bound him in prison for Herodias’ sake, his brother Philip’s wife: for he had married her.

18For John had said unto Herod, It is not lawful for thee to have thy brother’s wife.
