1 Samuel 28:19

To-morrow shalt thou and thy sons be with me— Samuel predicts two things. I. That Saul, and his three sons who were with him in the camp, should be with him; i.e. should, like him, be in another world, or should die. II. That they should die on the morrow, or rather, very shortly; for that is the signification of the word מחר machar, in many places of Scripture. See Exodus 13:14 and Joshua 4:6. It is probable, however, that the word in this place may be taken in its literal sense of to-morrow. These predictions of Samuel evidently proved that he spoke by God's order; for he foretells, first, the victory of the Philistines; secondly, the death of Saul and his sons; and thirdly, the advantages which the Philistines should derive from their victory. See chap. 1 Samuel 31:7. And it is surprising, that after such plain predictions as these, which could come only from God, any person should imagine that this apparition of Samuel was either a human or a diabolical imposture.
