For that which could not hinder a man from promising, ought not to be admitted as a hindrance of performing.
Right To The End, Containeth Right To The Means He that transferreth any Right, transferreth the Means of enjoying it, as farre as lyeth in his power.

As he that selleth Land, is understood to transferre the Herbage, and whatsoever growes upon it; Nor can he that sells a Mill turn away the Stream that drives it.

And they that give to a man The Right of government in Soveraignty, are understood to give him the right of levying mony to maintain Souldiers; and of appointing Magistrates for the administration of Justice.
No Covenant With Beasts To make Covenant with bruit Beasts, is impossible; because not understanding our speech, they understand not, nor accept of any translation of Right; nor can translate any Right to another; and without mutuall acceptation, there is no Covenant.
Nor With God Without Speciall Revelation To make Covenant with God, is impossible, but by Mediation of such as God speaketh to, either by Revelation supernaturall, or by his Lieutenants that govern under him, and in his Name; For otherwise we know not whether our Covenants be accepted, or not.

And therefore they that Vow any thing contrary to any law of Nature, Vow in vain; as being a thing unjust to pay such Vow.

And if it be a thing commanded by the Law of Nature, it is not the Vow, but the Law that binds them.
No Covenant, But Of Possible And Future The matter, or subject of a Covenant, is alwayes something that falleth under deliberation; (For to Covenant, is an act of the Will; that is to say an act, and the last act, of deliberation;) and is therefore alwayes understood to be something to come; and which is judged Possible for him that Covenanteth, to performe.
And therefore, to promise that which is known to be Impossible, is no Covenant.
