1 Samuel 28:17-19
17 He has done to you exactly as He told you through me, for He has wrestled the kingdom away from you in order to give it to your neighbor, David. 18 You did not obey the Eternal One’s orders to be an agent of His wrath on Amalek. That is why He has brought these circumstances upon you today. 19 And that is not all. He will hand you and your kingdom over to the Philistines. Tomorrow you and your sons will be where I am. The Eternal One will hand your entire army over to the Philistines.
