1 Samuel 18:8-14

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.

12Saul was afraid of David, because the Lord was with David but had departed from Saul.

13So he sent David away from him and gave him command over a thousand men, and David led the troops in their campaigns.

14In everything he did he had great success, because the Lord was with him.
