Mark 6:17-18 (NIV)
For Herod himself had given orders to have John arrested, and he had him bound and put in prison. He did this because of Herodias, his brother Philip’s wife, whom he had married. [18] For John had been saying to Herod, “It is not lawful for you to have your brother’s wife.”

Sigh.

The Bible does not tell us how John felt about confronting Herod’s sin. He was a sold out guy–locusts and honey and desert not being the marks of a casual faith. But he must have know that criticizing Herod for incest might be dangerous.

For John, God’s law trumps Herod’s or Rome’s. And he is right.

It all depends on who is the king and for how long.
