1 Samuel 18:5-9

5So 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.

6As 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.

7The women sang as they played and danced, saying, “Saul has slain his thousands, And David his ten thousands.”

8Then 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?”

9Saul looked at David with suspicion [and jealously] from that day forward.
