Mark 6:19-21

So Herodias nursed a grudge against John and wanted to kill him. But she was not able to, because Herod feared John and protected him, knowing him to be a righteous and holy man. When Herod heard John, he was greatly puzzled; yet he liked to listen to him. Finally the opportune time came. On his birthday Herod gave a banquet for his high officials and military commanders and the leading men of Galilee.
