When we think about the deeper meaning of the song, the composition 'Naomi Wise' by Bob Dylan narrates a fateful story full of treachery and murder. Through its lines, a woman, Naomi, is tricked and slain by a man, John Lewis, who is then arrested and punished for his crime. The metaphor of 'deep waters that flow through the land' is used to represent not only the irrevocable consequences of his deed but also the heavy burden of guilt that comes with it. Generally, the lyrics of Naomi Wise express feelings of despair, loss, etc. At the same time, the song points out the dimensions of betrayal along with the violence, desperation, and pleas, plus the consequences of one's actions. There are violent and death themes in the lyrics, including the presence of drowning and a character getting thrown into deep water, which may not be appropriate for kids below 13. Thus, the adult themes and the severity of the violence are enough reason for a PG-13 rating.
