 If a Covenant be made, wherein neither of the parties performe presently, but trust one another; in the condition of meer Nature, (which is a condition of Warre of every man against every man,) upon any reasonable suspition, it is Voyd; But if there be a common Power set over them bothe, with right and force sufficient to compell performance; it is not Voyd. For he that performeth first, has no assurance the other will performe after; because the bonds of words are too weak to bridle mens ambition, avarice, anger, and other Passions, without the feare of some coerceive Power; which in the condition of meer Nature, where all men are equall, and judges of the justnesse of their own fears cannot possibly be supposed. And therefore he which performeth first, does but betray himselfe to his enemy; contrary to the Right (he can never abandon) of defending his life, and means of living.
