1 Samuel 18:5-16

So David went out wherever Saul sent him, and he acted wisely and prospered; and Saul appointed him over the men of war. And it pleased all the people and also Saul’s servants. As they were coming [home], when David returned from killing the Philistine, the women came out of all the cities of Israel, singing and dancing, to meet King Saul with tambourines, [songs of] joy, and musical instruments. The women sang as they played and danced, saying, “Saul has slain his thousands, And David his ten thousands.” Then Saul became very angry, for this saying displeased him; and he said, “They have ascribed to David ten thousands, but to me they have ascribed [only] thousands. Now what more can he have but the kingdom?” Saul looked at David with suspicion [and jealously] from that day forward. Now it came about on the next day that an evil spirit from God came forcefully on Saul, and he raved [madly] inside his house, while David was playing the harp with his hand, as usual; and there was a spear in Saul’s hand. Saul hurled the spear, for he thought, “I will pin David to the wall.” But David evaded him twice. Now Saul was afraid of David, because the LORD was with him, but had departed from Saul. So Saul had David removed from his presence and appointed him as his commander of a thousand; and he publicly associated with the people. David acted wisely and prospered in all his ways, and the LORD was with him. When Saul saw that he was prospering greatly, he was afraid of him. But all Israel and Judah loved David, because he publicly associated with them.
