1 Samuel 18:8-11

18:8 This made Saul very angry. The statement displeased him and he thought, “They have attributed to David tens of thousands, but to me they have attributed only thousands. What does he lack, except the kingdom?” 18:9 So Saul was keeping an eye on David from that day onward.

18:10 The next day an evil spirit from God rushed upon Saul and he prophesied within his house. Now David was playing the lyre that day. There was a spear in Saul’s hand, 18:11 and Saul threw the spear, thinking, “I’ll nail David to the wall!” But David escaped from him on two different occasions.
