Mark 6:19-21

Therefore Herodias held it against him and wanted to kill him, but she could not; 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. Then an opportune day came when Herod on his birthday gave a feast for his nobles, the high officers, and the chief men of Galilee.
