1 Samuel 28:7

Seek me a woman that hath a familiar spirit. — He was left alone to himself, and now the last spark of life, the religious zeal which he had once shown even to excess, then also vanished; or, rather. as must always be the case when it has thus swerved from the moral principle which alone can guide it, was turned into a wild and desperate superstition. The wizards and familiar spirits, whom in a fit of righteous indignation he had put out of the land, now became his only resource —

Flectere si nequeo supcros, Acheronte movebo.

STANLEY: Jewish Church, vol. ii., Lect. 21

Behold, there is a woman that hath a familiar spirit at En-dor. — One of these women, mistress or possessor of an ôb, or familiar spirit, who apparently was well known, dwelt at or was left at Endor. “East of Nain is a village of mud-huts, with hedges of prickly pear. This is En-dor, famous in connection with the tragic history of the death of Saul. The adventurous character of Saul’s night journey is very striking, when we consider that for the king to get to En-dor he had to pass the hostile camp, and would probably creep round the eastern shoulder of the hill hidden by the undulations of the ground.” — Conder: Tent Life in Palestine. The distance from the camp of Israel on Gilboa to En-dor was about ten miles further, owing perhaps to the circuit they would have to make round the camp of the Philistines. Jewish tradition speaks of the “two men” who accompanied Saul as Abner and Amasa, and further mentions that the witch of En-dor was the mother of the great Abner. If this be true, it would account for her having escaped the general pursuit after witches mentioned above in the early days of Saul.
