1 Samuel 18:6-13
English Standard Version
Chapter 18
6As they were coming home, when David returned from striking down the Philistine, the women came out of all the cities of Israel, singing and dancing, to meet King Saul, with tambourines, with songs of joy, and with musical instruments. 7And the women sang to one another as they celebrated, "Saul has struck down his thousands, and David his ten thousands."
8And Saul was very angry, and this saying displeased him. He said, "They have ascribed to David ten thousands, and to me they have ascribed thousands, and what more can he have but the kingdom?"
9And Saul eyed David from that day on.
