1 Samuel 18:5-9

And David went out whithersoever Saul sent him, and behaved himself wisely: and Saul set him over the men of war, and it was good in the sight of all the people, and also in the sight of Saul’s servants. And it came to pass as they came, when David returned from the slaughter of the Philistine, that the women came out of all the cities of Israel, singing and dancing, to meet king Saul, with timbrels, with joy, and with instruments of music. And the women sang one to another as they played, and said, Saul hath slain his thousands, And David his ten thousands. And Saul was very wroth, and this saying displeased him; and he said, They have ascribed unto David ten thousands, and to me they have ascribed but thousands: and what can he have more but the kingdom? And Saul eyed David from that day and forward.
