1 Samuel 28:2-4

Amplified Bible

² David said to Achish, “All right, you shall know what your servant can do.” So Achish said to David, “Therefore I will make you my bodyguard for life.”

³ Now Samuel had died, and all Israel had mourned for him and buried him in Ramah, his own city. And Saul had removed the mediums and the spiritists (soothsayers) from the land. ⁴ The Philistines assembled and came and camped at Shunem; and Saul gathered all the Israelites and they camped at Gilboa.
