1 Samuel 18:8-14

8And Saul was very angry, and this saying displeased him. He said, "They have ascribed to David ten thousands, and to me they have ascribed thousands, and what more can he have but the kingdom?"

9And Saul eyed David from that day on.

10The next day a harmful spirit from God rushed upon Saul, and he raved within his house while David was playing the lyre, as he did day by day. Saul had his spear in his hand.

11And Saul hurled the spear, for he thought, "I will pin David to the wall." But David evaded him twice.

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

13So Saul removed him from his presence and made him a commander of a thousand. And he went out and came in before the people.

14And David had success in all his undertakings, for the Lord was with him.
