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. Mark 6:19-20
An illegitimately married couple, and she wants to kill the messenger while he wants to keep the man around. That should cause a bit of tension in the household.
In between the recording of the miracles and teachings of Jesus, we get how things are in the world. A queen who saw the easier way out was to murder a man. A king who could be easily outmaneuvered by his lust. A daughter who was a willing tool to her mother's ends. And, a just and holy man who was such a refreshing change for the time that the king liked having him around. When the good news of Jesus meets the way of the world, there will be a resounding clash. Some will hear it gladly, but may never believe. Others want to kill the messenger.
To God be the glory!
