1 Samuel 28
Now David and his men accompanied the Philistines in battle against Israel and Saul was afraid with terror in his heart. Saul "inquired of the Lord, but the Lord did not answer him", so he instead called for a medium for a "spiritual" consultation. Saul instructed the woman who was a medium to "bring up" the spirit of Samuel. Saul asked Samuel for guidance, since the Lord had departed from him, but Samuel just reminded him that "the Lord has done what was predicted through me... torn the kingdom out of your hands and given it to David... because you did not obey the Lord". Upon hearing these things from Samuel, Saul was greatly shaken and was further filled with fear.
