1 Samuel 28:5-7

When Saul saw the vast Philistine army, he became frantic with fear. He asked the LORD what he should do, but the LORD refused to answer him, either by dreams or by sacred lots or by the prophets. Saul then said to his advisers, “Find a woman who is a medium, so I can go and ask her what to do.” His advisers replied, “There is a medium at Endor.”
