1 Samuel 18:8-10

Darby Translation

⁸ And Saul was very wroth, and that saying was evil in his sight; and he said, They have ascribed to David ten thousands, but to me they have ascribed the thousands; and [what] is there more for him but the kingdom?

⁹ And Saul eyed David from that day and forward.

¹⁰ And it came to pass the next day that an evil spirit from God came upon Saul, and he prophesied in the midst of the house, but David played with his hand, as on other days; and the spear was in Saul's hand.
