1 Samuel 18:7-9

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.
