II. What there is in the idea of a covenant, as we generally understand the word, when applied to signify a contract between man and man. In this case, there are two parties, one of which is said to stipulate, or enter into a covenant with the other, in which he makes a proposal, that he will confer some favours on him, upon certain conditions, provided he will oblige himself to fulfil them; and the other party complies with the proposal made, and, in expectation of those advantages, consents to fulfil the conditions enjoined, and accordingly is said to re-stipulate; as when a person engages another to be his servant, and to give him a reward for his service; and the other consents to serve him, in expectation of the wages which he engages to give him: in this case, each party is supposed to be possessed of something, which the other has no right to, but by virtue of this contract made between them: thus the servant has no right to the rewards, which his master promises, nor has the master any right to his service, but by mutual consent. Each party also proposes some advantage to himself, and therefore, when they enter into this agreement, they are supposed, in some respects, to stand on a level with each other. No one will enter into a covenant with another, for the performing that which he had an antecedent right to; nor will any one engage to perform any service, as a condition of his receiving those benefits, which he had a right to, without any such condition enjoined on him. Moreover, when two parties are said to enter into covenant with one another, they are supposed, in some respects, to stand in need of some things, which they had before no right to; one party needs the reward proposed; the other, the service which he enjoins, as a condition of his bestowing it. These things are generally supposed, and contained in contracts between man and man.
