18For John had said unto
Herod, It is not lawful for thee to have thy brother’s wife.  19Therefore Herodias had a quarrel against him, and would have killed
him; but she could not:  20For Herod
feared John, knowing that he was a just man and an holy, and observed him; and when he heard him, he did
many things, and heard him gladly. (Mark
6:18-20, King James
Version)
