And the woman said unto him,.... Not knowing who he was:

behold, thou knowest what Saul hath done; for by his speech and habit she perceived he was an Israelite, and so must be acquainted with what had passed in the nation, especially of a public nature, and which made a great noise, as doubtless this, lid:

how he both cut off those that have familiar spirits, and the wizards,

out of the land; as many of them as he had knowledge of, or information about; and by this it appears that he did not merely expel them his dominions, but he put them to death, according to the law of God, Exodus 22:18; so the putting them out of the land, 1 Samuel 28:3, was putting them to death, and the woman's after reasoning confirms this: one should think for Saul to be told this to his face must fill him with shame and confusion, and his conscience must accuse him of sin and folly to make this attempt; and he must stand self-convicted and self-condemned; and it was enough to have deterred him from pursuing his scheme, had not his heart been strangely hardened:

wherefore then layest thou a snare for my life, to cause me to die? she suspected that Saul and his men were persons that came to entrap her; that when they had prevailed upon her to exercise her art, would turn informers against her, to the taking away of her life, it being death to practise it.

Such a demand placed the woman in difficulty. As Saul had driven the necromantists out of the land, she was afraid that the unknown visitor (for it is evident from 1 Samuel 28:12 that she did not recognise Saul at first) might be laying a snare for her soul with his request, to put her to death, i.e., might have come to her merely for the purpose of spying her out as a conjurer of the dead, and then inflicting capital punishment upon her according to the law (Leviticus 20:27).

And the woman said unto him, Behold, thou knowest what Saul hath done, how he hath cut off those that have familiar spirits, and the wizards, out of the land: wherefore then layest thou a snare for my life, to cause me to die?

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, De 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.
