1 Samuel 18:8-11

8And 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?

9And Saul eyed David from that day and forward.

10And it came to pass the next day that an evil spirit from 1God 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.

11And Saul cast the spear, and thought, I will smite David and the wall. But David turned away from him twice.
