1 Samuel 28

1 Samuel 28:14

And that the souls survive, I have shown to you from the fact that the soul of Samuel was called up by the witch, as Saul demanded. And it appears also, that all the souls of similar righteous men and prophets fell under the dominion of such powers, as is indeed to be inferred from the very facts in the case of that witch. Hence also God by His Son teaches us for whose sake these things seem to have been done, always to strive earnestly, and at death to pray that our souls may not fall into the hands of any such power. — Dialogue with Trypho, Chapter CV
