REWARD, is either of Gift, or by Contract. When by Contract, it is called Salary, and Wages; which is benefit due for service performed, or promised. When of Gift, it is benefit proceeding from the Grace of them that bestow it, to encourage, or enable men to do them service. And therefore when the Soveraign of a Common-wealth appointeth a Salary to any publique Office, he that receiveth it, is bound in Justice to performe his office; otherwise, he is bound onely in honour, to acknowledgement, and an endeavour of requitall. For though men have no lawfull remedy, when they be commanded to quit their private businesse, to serve the publique, without Reward, or Salary; yet they are not bound thereto, by the Law of Nature, nor by the institution of the Common-wealth, unlesse the service cannot otherwise be done; because it is supposed the Soveraign may make use of all their means, insomuch as the most common Souldier, may demand the wages of his warrefare, as a debt.
