1 Samuel 28:16-19

16Then said Samuel, Why then dost thou ask of me, seeing the LORD hath departed from thee, and hath become thy enemy? 17And the LORD hath done to him, as he spoke by me: for the LORD hath torn the kingdom out of thy hand, and given it to thy neighbour, even to David:12 18Because thou didst not obey the voice of the LORD, nor execute his fierce wrath upon Amalek, therefore hath the LORD done this thing to thee this day. 19Moreover the LORD will also deliver Israel with thee into the hand of the Philistines: and to morrow shalt thou and thy sons be with me: the LORD also shall deliver the host of Israel into the hand of the Philistines.
