Another of the laws of nature is, to _perform contracts_, or _to keep trust_. For it hath been showed in the foregoing chapter, that the law of nature commands every man, as a thing necessary, to obtain peace, to convey certain rights from each to other; and that this, as often as it shall happen to be done, is called a contract. But this is so far forth only conducible to peace, as we shall perform ourselves what we contract with others shall be done or omitted; and in vain would contacts be made, unless we stood to them. Because therefore to stand to our covenants, or to keep faith, is a thing necessary for the obtaining of peace; it will prove, by the second article of the second chapter, to be a precept of the natural law.
