1 Samuel 18:8-11

8Saul was very angry; this refrain displeased him greatly. “They have credited David with tens of thousands,” he thought, “but me with only thousands. What more can he get but the kingdom?”

9And from that time on Saul kept a close eye on David.

10The next day an evil spirit from God came forcefully on Saul. He was prophesying in his house, while David was playing the lyre, as he usually did. Saul had a spear in his hand

11and he hurled it, saying to himself, “I’ll pin David to the wall.” But David eluded him twice.
