1 Samuel 18:5-8, 10-11

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?”

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.
