hath vowed to forbear wine, or feasting, or marriage, is discharged, if his prince, or captain, or masters be against it. Jonathan and David were under an oath of friendship, (called the Lord's oath, 2 Sam. xxi. 7). Saul as a parent could not discharge Jonathan, as being a man at full age. Quære whether Saul as a king being against it, did null the oath to David and Jonathan? No; the Scripture showeth the contrary. 8. Because else that benefit which God extendeth only to a weaker sort, would extend to any, the wisest and most learned persons through the world, whose vows to God, even for the afflicting of their own souls, may be nulled by the king or other superiors. Many such reasons are urged in this case. 3. It is uncertain whether this chapter extend to assertory or testimonial oaths (if not certain that it doth not): it speaketh but of binding their souls to God, which is to offer or do something which by error may prove prejudicial to them. But if a parent or husband (much more a king or general) might nullify all the testimonial oaths of their inferiors that are given in judgment, or discharge all their subjects from the guilt of all the lies or false oaths which they shall take, it would make a great change in the morality of the world. 4. It is not past all controversy how far this law is yet in force: seeing the Mosaical law as such is abrogated; this can be now no further in force than as it is the law of nature, or some way confirmed or revived by Christ. The equity seemeth to be natural. _Rule_ XXXI. It is certain that whoever this power of disannulling vows belongeth to, and to whomsoever it may be given, that it extendeth not to discharge us from the promise or vow of that which is antecedently our necessary duty, by the law of God. Else they should dispense with the law of God, when none but the lawgiver can relax or dispense with his laws (unless it be one superior to the lawgiver): therefore none can dispense with the laws of God. But I speak this but of a duty necessary also as a means to our salvation, or the good of others, or the honouring of God: for otherwise as to some smaller things, the duty may be such as man cannot dispense with, and yet a vow to do that duty may be unnecessary and sinful: as if I swear to keep all the law of God, and never to sin, or never to think a sinful thought; to do this is good, but to vow it is bad, because I may foreknow that I shall break it.
