7 Then Saul said to his servants, "Seek out for me a woman who is a medium, so that I may go to her and inquire of her." His servants said to him, "There is a medium at Endor." 8 So Saul disguised himself and put on other clothes and went there, he and two men with him. They came to the woman by night. And he said, "Consult a spirit for me, and bring up for me the one whom I name to you." 9 The woman said to him, "Surely you know what Saul has done, how he has cut off the mediums and the wizards from the land. Why then are you laying a snare for my life to bring about my death?" 10 But Saul swore to her by the Lord, "As the Lord lives, no punishment shall come upon you for this thing." 11 Then the woman said, "Whom shall I bring up for you?" He answered, "Bring up Samuel for me." 12 When the woman saw Samuel, she cried out with a loud voice; and the woman said to Saul, "Why have you deceived me? You are Saul!" 13 The king said to her, "Have no fear; what do you see?" The woman said to Saul, "I see a divine being coming up out of the ground." 14 He said to her, "What is his appearance?" She said, "An old man is coming up; he is wrapped in a robe." So Saul knew that it was Samuel, and he bowed with his face to the ground, and did obeisance.
15 Then Samuel said to Saul, "Why have you disturbed me by bringing me up?" Saul answered, "I am in great distress, for the Philistines are warring against me, and God has turned away from me and answers me no more, either by prophets or by dreams; so I have summoned you to tell me what I should do." 16 Samuel said, "Why then do you ask me, since the Lord has turned from you and become your enemy? 17 The Lord has done to you just as he spoke by me; for the Lord has torn the kingdom out of your hand, and given it to your neighbor, David. 18 Because you did not obey the voice of the Lord, and did not carry out his fierce wrath against Amalek, therefore the Lord has done this thing to you today. 19 Moreover the Lord will give Israel along with you into the hands of the Philistines; and tomorrow you and your sons shall be with me; the Lord will also give the army of Israel into the hands of the Philistines."
20 Immediately Saul fell full length on the ground, filled with fear because of the words of Samuel; and there was no strength in him, for he had eaten nothing all day and all night. 21 The woman came to Saul, and when she saw that he was terrified, she said to him, "Your servant has listened to you; I have taken my life in my hand, and have listened to what you have said to me. 22 Now therefore, you also listen to your servant; let me set a morsel of bread before you. Eat, that you may have strength when you go on your way." 23 He refused, and said, "I will not eat." But his servants, together with the woman, urged him; and he listened to their words. So he got up from the ground and sat on the bed. 24 Now the woman had a fatted calf in the house. She quickly slaughtered it, and she took flour, kneaded it, and baked unleavened cakes. 25 She put them before Saul and his servants, and they ate. Then they rose and went away that night.

Commentary on 1 Samuel 28:7-19
(Read 1 Samuel 28:7-19)
When we go from the plain path of duty, every thing draws us further aside, and increases our perplexity and temptation. Saul desires the woman to bring one from the dead, with whom he wished to speak; this was expressly forbidden, Deuteronomy 18:11. All real or pretended witchcraft or conjuration, is a malicious or an ignorant attempt to gain knowledge or help from some creature, when it cannot be had from the Lord in the path of duty. While Samuel was living, we never read of Saul's going to advise with him in any difficulties; it had been well for him if he had. But now he is dead, "Bring me up Samuel." Many who despise and persecute God's saints and ministers when living, would be glad to have them again, when they are gone. The whole shows that it was no human fraud or trick. Though the woman could not cause Samuel's being sent, yet Saul's inquiry might be the occasion of it. The woman's surprise and terror proved that it was an unusual and unexpected appearance. Saul had despised Samuel's solemn warnings in his lifetime, yet now that he hoped, as in defiance of God, to obtain some counsel and encouragement from him, might not God permit the soul of his departed prophet to appear to Saul, to confirm his former sentence, and denounce his doom? The expression, "Thou and thy sons shall be with me," means no more than that they shall be in the eternal world. There appears much solemnity in God's permitting the soul of a departed prophet to come as a witness from heaven, to confirm the word he had spoken on earth.
Commentary on 1 Samuel 28:20-25
(Read 1 Samuel 28:20-25)
Those that expect any good counsel or comfort, otherwise than from God, and in the way of his institutions, will be as wretchedly disappointed as Saul. Though terrified even to despair, he was not humbled. He confessed not his sins, offered no sacrifices, and presented no supplications. He does not seem to have cared about his sons or his people, or to have attempted any escape; but in sullen despair he rushed upon his doom. God sets up a few such beacons, to warn men not to stifle convictions, or despise his word. But while one repenting thought remains, let no sinner suppose himself in this case. Let him humble himself before God, determined to live and die beseeching his favour, and he will succeed.
