1 Samuel 28:1-6

Later, the Philistines gathered their armies to fight against Israel. Achish said to David, “You understand that you and your men must join my army.” David answered, “You will see for yourself what I, your servant, can do!” Achish said, “Fine, I’ll make you my permanent bodyguard.” Now Samuel was dead, and all the Israelites had shown their sadness for him. They had buried Samuel in his hometown of Ramah. And Saul had forced out the mediums and fortune-tellers from the land. The Philistines came together and made camp at Shunem. Saul gathered all the Israelites and made camp at Gilboa. When he saw the Philistine army, he was afraid, and his heart pounded with fear. He prayed to the LORD, but the LORD did not answer him through dreams, Urim, or prophets.
