8 So Saul disguised himself and put on other garments and went, he and two men with him. And they came to the woman by night. And he said, "Divine for me by a spirit and bring up for me whomever I shall 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 necromancers from the land. Why then are you laying a trap 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 said, "Bring up Samuel for me."

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.
