The prophet Nathan: The name signifies Gift. A life clean. Compassionate. Wise. Had more than reputation, had integrity. Thus could point the "finger in the face of the King"
David could have: 1. Ordered Nathan killed 2. Told him to leave and stayed quiet. 3. Expelled him from the palace forever. 4. Justify himself with the prophet.
The correct one is: sin - confession - resistance. Illustration: Brothers John and Mary lived in a small farm. John killed one of his mother’s pretty duck. Only Mary knew. John became Mary’s slave. "John, watch the duck".
