1 Samuel 18:6-9

As they returned home, after David had killed the Philistine, the women poured out of all the villages of Israel singing and dancing, welcoming King Saul with tambourines, festive songs, and lutes. In playful frolic the women sang, Saul kills by the thousand, David by the ten thousand! This made Saul angry—very angry. He took it as a personal insult. He said, “They credit David with ‘ten thousands’ and me with only ‘thousands.’ Before you know it they’ll be giving him the kingdom!” From that moment on, Saul kept his eye on David.
