'Sang' in the Bible

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

Saul was very angry and he did not like what the women sang. He told himself, "They have attributed tens of thousands to David, but to me they have attributed thousands. What else can he have but the kingdom?"

The officials of Achish told him, "Isn't this David, king of the land? Isn't this the one about whom they sang as they danced, "Saul has struck down his thousands, but David his ten thousands'?"

Is not this David, of whom they sang one to another in dances, saying, Saul slew his thousands, and David his ten thousands?
