'Tens' in the Bible

The women who were playing the music sang, "Saul has struck down his thousands, but David his tens of thousands!"

This made Saul very angry. The statement displeased him and he thought, "They have attributed to David tens of thousands, but to me they have attributed only thousands. What does he lack, except the kingdom?"

The servants of Achish said to him, "Isn't this David, the king of the land? Isn't he the one that they sing about when they dance, saying, 'Saul struck down his thousands, But David his tens of thousands'?"

Isn't this David, of whom they sang as they danced, 'Saul has struck down his thousands, but David his tens of thousands'?"
