1 Samuel 18:7-9

⁷The women sang as they played, and said,

“Saul has slain his thousands,

And David his ten thousands.”

⁸Then Saul became very angry, for this lyric displeased him; and he said, “They have given David credit for ten thousands, but to me they have given credit for only thousands! Now what more can he have but the kingdom?” ⁹And Saul eyed David with suspicion from that day on.
