'Tens' in the Bible

As they celebrated, the women sang:Saul has killed his thousands,but David his tens of thousands.

Saul was furious and resented this song. “They credited tens of thousands to David,” he complained, “but they only credited me with thousands. What more can he have but the kingdom?”

But Achish’s servants said to him, “Isn’t this David, the king of the land? Don’t they sing about him during their dances:Saul has killed his thousands,but David his tens of thousands?”

Isn’t this the David they sing about during their dances:Saul has killed his thousands,but David his tens of thousands?”
