1 Samuel 18:7-9

King James Version

⁷ And the women answered one another as they played, and said, Saul hath slain his thousands, and David his ten thousands.

⁸ And Saul was very wroth, and the 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?

⁹ And Saul eyed David from that day and forward.
