1 Samuel 18:8-10

New Century Version

⁸ The women’s song upset Saul, and he became very angry. He thought, “The women say David has killed tens of thousands, but they say I have killed only thousands. The only thing left for him to have is the kingdom!” ⁹ So Saul watched David closely from then on, because he was jealous.

¹⁰ The next day an evil spirit from God rushed upon Saul, and he prophesied in his house. David was playing the harp as he usually did, but Saul had a spear in his hand.
