1. A grim message (15-19)

Saul wanted dead Samuel to tell him what to do (15). Samuel's spirit gave Saul a true message: the LORD has departed from you and has become your enemy; the kingdom is going to David as I already said (15:28); you disobeyed God; Israel will lose the battle and you will die. It was all bad news. There was no advice about what to do. Consulting the medium was a bad idea.

2. They ate and left (20-25)

After hearing the spirit's prediction, Saul was even more afraid and lost all his strength. The psychic persuaded Saul to eat; she butchered her fattened calf and he ate and then left. There was no mention of Saul repenting or crying out to God in prayer. Listening to a fortune-teller and eating beef and unleavened bread are not seeking God and following his will.
