1 And Sarah was an hundred and seven and twenty years old: these were the years of the life of Sarah. 2 And Sarah died in Kirjath-arba; the same is Hebron in the land of Canaan: and Abraham came to mourn for Sarah, and to weep for her. 3 And Abraham stood up from before his dead, and spake unto the sons of Heth, saying, 4 I am a stranger and a sojourner with you: give me a possession of a buryingplace with you, that I may bury my dead out of my sight. 5 And the children of Heth answered Abraham, saying unto him, 6 Hear us, my lord: thou art a mighty prince among us: in the choice of our sepulchres bury thy dead; none of us shall withhold from thee his sepulchre, but that thou mayest bury thy dead. 7 And Abraham stood up, and bowed himself to the people of the land, even to the children of Heth. 8 And he communed with them, saying, If it be your mind that I should bury my dead out of my sight; hear me, and intreat for me to Ephron the son of Zohar, 9 That he may give me the cave of Machpelah, which he hath, which is in the end of his field; for as much money as it is worth he shall give it me for a possession of a buryingplace amongst you. 10 And Ephron dwelt among the children of Heth: and Ephron the Hittite answered Abraham in the audience of the children of Heth, even of all that went in at the gate of his city, saying, 11 Nay, my lord, hear me: the field give I thee, and the cave that is therein, I give it thee; in the presence of the sons of my people give I it thee: bury thy dead. 12 And Abraham bowed down himself before the people of the land. 13 And he spake unto Ephron in the audience of the people of the land, saying, But if thou wilt give it, I pray thee, hear me: I will give thee money for the field; take it of me, and I will bury my dead there. 14 And Ephron answered Abraham, saying unto him, 15 My lord, hearken unto me: the land is worth four hundred shekels of silver; what is that betwixt me and thee? bury therefore thy dead. 16 And Abraham hearkened unto Ephron; and Abraham weighed to Ephron the silver, which he had named in the audience of the sons of Heth, four hundred shekels of silver, current money with the merchant. 17 And 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 18 Unto Abraham for a possession in the presence of the children of Heth, before all that went in at the gate of his city. 19 And after this, Abraham buried Sarah his wife in the cave of the field of Machpelah before Mamre: the same is Hebron in the land of Canaan. 20 And the field, and the cave that is therein, were made sure unto Abraham for a possession of a buryingplace by the sons of Heth.
[AD 580] Martin of Braga on Genesis 23:2
A brother asked an old man, “What shall I do for my sins?” He replied, “He who desires to be free from his sins shall be freed from them by weeping, and he who wishes to build virtues in himself will build them by weeping. Even the Scriptures are composed of mourning, for our fathers said to their disciples, ‘Wail.’ There is no other way to life except this.”A brother asked an old man, “What shall I do, father?” He replied, “When Abraham entered the Promised Land, he first bought a tomb for himself, and near the tomb he made sure of land for a possession.” The brother said to him, “What is a tomb?” He answered, “A place of mourning and weeping.”

[AD 215] Clement of Alexandria on Genesis 23:6
The subjects by a free decision obey the good man in their enthusiasm for virtue. The philosopher Plato puts forward happiness as the goal of life and says it consists in “the greatest possible likeness to God.” This may come from his going along with the general principles of the law (Philo the Pythagorean says in expounding the text of Moses, “Great natures free from passion aim fairly successfully in the direction of truth”).

[AD 407] John Chrysostom on Genesis 23:6
Sarah’s death was the occasion for the patriarch’s first instance of acquiring land. Sacred Scripture in fact shows us in every case the patriarch’s virtue, in that he passed all his time as an alien and a nomad. And it mentions this latest item for us to learn that the man who enjoyed so much assistance from on high, who had become so famous and had increased in number to such a vast multitude, could not call a place his own, unlike many people today, who give all their attention to acquiring land, whole towns and great wealth beyond telling. You see, he had sufficient riches in his attitude, and he put no store by these other things. Let those heed this who in the twinkling of an eye take to themselves every conceivable thing and, so to say, stretch out in all directions their passion for avarice. Let them also imitate the patriarch, who had not even a place to inter Sarah’s remains until, under pressure of very necessity, he bought the field and cave from the Hittites. For proof that he was in fact respected by the inhabitants of Canaan, listen to the words addressed to him by the Hittites: “You are king among us by God’s appointment; bury your dead in our best tombs. None of us, after all, will keep this tomb from you.”

[AD 407] John Chrysostom on Genesis 23:13
Notice, however, how the good man instructs even those people with his characteristic common sense, through his very actions, by forbearing to take possession of it before paying a just price. “Even if you for your part … have proved so kindly disposed toward me, I still cannot bring myself to take the tomb from you unless first I pay the proper price.” He gave them money, the text says, took possession of the tomb “and buried his wife Sarah in the double cave of the field overlooking Mamre.” The man who was so famous and respected, who enjoyed such confidence with God and was the object of such attention from everyone, so to say, in that place that even the Hittites called him king—he owned not even one foot of land. Hence blessed Paul also celebrated this good man’s virtue in writing these words: “By faith Abraham dwelt in the land of promise, like a foreigner living in tents with Isaac and Jacob, coheirs of the same promise.” Then to teach us how it was through faith that he dwelt there, he added, “He looked forward, you see, to the city built on foundations of which the builder and creator was God.” In the hope of things to come, he is saying, he overlooked present realities, and, in the expectation of greater things, he set less store by those of this life—and this before the law and the age of grace.So what excuse will we have, tell me, who despite such wonderful promises and guarantees of ineffable blessings hanker for present realities, buying up property, ever concerned for our image, amassing all these possessions out of greed and avarice and fulfilling in practice what the blessed prophet said in his lament, “Woe to those who pile house on house and add property to property for the purpose of robbing their neighbor of something.” Do we not see this happening each day—widows being robbed, orphans despoiled and the weak oppressed by the strong? This good man, on the contrary, did not behave in that fashion; instead, he insisted on buying the tomb, and, when he saw those from whom he sought it ready and willing to hand it over, he could not bring himself to accept it before he paid the right price.

[AD 410] Prudentius on Genesis 23:19
This is the lodging place of the Lord, where an oak branch at Mamre
Covered the pastoral roof of the ancient seer; in this hospice
Sarah laughed at the joy of bearing a child in her old age
And at the faith her venerable husband could have in the marvel.
Abraham purchased a field wherein he might bury his wife’s bones,
Inasmuch as justice and faith on the earth dwell as strangers:
This is the cave for which he expended a great sum of money,
To prepare a fit resting place for his wife’s holy ashes.

[AD 407] John Chrysostom on Genesis 23:20
With this in mind, dearly beloved, let us who live in the age of grace imitate the man who lived before the law, not burn with desire for more and heap up for ourselves to a greater and more intense degree the fire that cannot be extinguished and the flame that is intolerable. We will hear, in fact, if we persist in such awful deeds of injustice and avarice, the words spoken to that notorious rich man, “Fool, this night they are looking for your soul from you; but as for what you have put aside, whom will it belong to?” I mean, what is the reason, dearly beloved, that you are anxious to amass so many things that you will shortly leave here, due as you are to be snatched away from the scene, not only powerless to gain any advantage from them but even saddled with the burden of sins on your own shoulders, at this stage too late for worthwhile repentance? While the goods you have amassed with avarice oftentimes finish even in the hands of enemies, you yourself will be required to give an account of them. So what folly would it be to labor for others’ benefit and pay the price for them yourself?

[AD 407] John Chrysostom on Genesis 23:20
Even if in the past, however, we have to this degree managed our affairs with indifference, now at least let us plan for what is needful and not simply be anxious to bedeck ourselves with the trappings of wealth, but rather pay much attention to doing good. After all, our being will not come to an end with this present life, nor shall we be always in exile; instead, before long we shall reach our true homeland. So let us do everything in the hope of not being found wanting there. I mean, what good is it to leave behind great wealth in foreign parts while wanting for bare necessities in our true country? Consequently let us strive, dearly beloved, while there is still time, to transfer there what we own in this foreign country. Although in fact the distance may be great, nevertheless the transfer is quite easy. You see, there are those ready to make the transfer, to travel there safely and deposit in a secure treasury whatever we are able to send ahead by means of them. I mean, the hands of the poor lay up in the treasuries of heaven what is given them by us. Since then the ease and security are so great, why do we delay and not rather with all haste act on this so that we will have those things at our disposal in the place where we most have need of them?
