'Dances' in the Bible

The servants of Achish said to him, "Isn't this David the king of the land? Didn't they sing one to another about him in dances, saying, 'Saul has slain his thousands, David his ten thousands?'"

Is not this David, of whom they sang one to another in dances, saying, 'Saul has slain his thousands, David his ten thousands?'"
