Again, his determination to hold it in perpetuity is evident not only from the nature of the property, but also from the formal purchase and conveyance of it--the complete and precise terms in which the transaction is completed. The narrative is careful to remind us again and again that the whole transaction was negotiated in the audience of the people of the land, of all those who went in at the gate, that the sale was thoroughly approved and witnessed by competent authorities. The precise subjects made over to Abraham are also detailed with all the accuracy of a legal document--"the field of Ephron, which was in Machpelah, which was before Mamre, the field and the cave which was therein, and all the trees that were in the field, that were in all the borders round about, were made sure unto Abraham for a possession in the presence of the children of Heth, before all that went in at the gate of his city." Abraham had no doubt of the friendliness of such men as Aner, Eshcol, and Mamre, his ancient allies, but he was also aware that the best way to maintain friendly relations was to leave no loophole by which difference of opinion or disagreement might enter. Let the thing be in black and white, so that there may be no misunderstanding as to terms, no expectations doomed to be unfulfilled, no encroachments which must cause resentment, if not retaliation. Law probably does more to prevent quarrels than to heal them. As statesmen and historians tell us that the best way to secure peace is to be prepared for war, so legal documents seem no doubt harsh and unfriendly, but really are more effective in maintaining peace and friendliness than vague promises and benevolent intentions. In arranging affairs and engagements one is always tempted to say, Never mind about the money, see how the thing turns out and we can settle that by-and-bye; or, in looking at a will, one is tempted to ask, of what strength is Christian feeling--not to say family affection--if all these hard-and-fast lines need to be drawn round the little bit of property which each is to have? But experience shows that this is false delicacy, and that kindliness and charity may be as fully and far more safely expressed in definite and legal terms than in loose promises or mere understandings. Again, Abraham's idea in purchasing this sepulchre is brought out by the circumstance that he would not accept the offer of the children of Heth to use one of their sepulchres. This was not pride of blood or any feeling of that sort, but the right feeling that what God had promised as His own peculiar gift must not seem to be given by men. Possibly no great harm might have come of it if Abraham had accepted the gift of a mere cave, or a shelf in some other man's burying-ground; but Abraham could not bear to think that any captious person should ever be able to say that the inheritance promised by God was really the gift of a Hittite.
