1 Samuel 18:8-10

Amplified Bible

⁸ Then Saul became very angry, for this saying ^[a]displeased him; and he said, “They have ascribed to David ten thousands, but to me they have ascribed [only] thousands. Now what more can he have but the kingdom?” ⁹ Saul looked at David with suspicion [and jealously] from that day forward.

Saul Turns against David

¹⁰ Now it came about on the next day that an evil spirit from God came forcefully on Saul, and he raved [madly] inside his house, while David was playing the harp with his hand, as usual; and there was a spear in Saul’s hand.
