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.

Wesley's Notes

23:4 I am a stranger and a sojourner with you - Therefore I am unprovided, and must become a suiter to you for a burying - place. This was one occasion which Abraham took to confess that he was a stranger and a pilgrim upon earth. The death of our relations should effectually mind us that we are not at home in this world. That I may bury my dead out of my sight - Death will make those unpleasant to our sight, who while they lived were the desire of our eyes. The countenance that was fresh and lively becomes pale and ghastly, and fit to be removed into the land of darkness.

Scofield Reference Notes

[1] buryingplace

Cf. Gen 33:19 50:13 Josh 24:32 Acts 7:15,16. A discrepancy in these statements has been fancied. It disappears entirely before the natural supposition that in the interval of about eighty years between the purchase by Abraham of the family sepulchre Gen 23:4-20 and Jacob's purchase Gen 33:19, the descendants of Hamor (or "Emmor," Acts 7:15,16 had resumed possession of the field in which the burial cave was situated. Instead of asserting an ancient title by inheritance, Jacob repurchased the field. Heth was the common ancestor.

Matthew Henry's Concise Commentary

23:1-13 The longest life must shortly come to a close. Blessed be God that there is a world where sin, death, vanity, and vexation cannot enter. Blessed be his name, that even death cannot part believers from union with Christ. Those whom we most love, yea, even our own bodies, which we so care for, must soon become loathsome lumps of clays, and be buried out of sight. How loose then should we be to all earthly attachments and adornments! Let us seek rather that our souls be adorned with heavenly graces. Abraham rendered honour and respect to the princes of Heth, although of the ungodly Canaanites. The religion of the Bible enjoins to pay due respect to all in authority, without flattering their persons, or countenancing their crimes if they are unworthy characters. And the noble generosity of these Canaanites shames and condemns the closeness, selfishness, and ill-humour of many that call themselves Israelites. It was not in pride that Abraham refused the gift, because he scorned to be beholden to Ephron; but in justice and in prudence. Abraham was able to pay for the field, and therefore would not take advantage of Ephron's generosity. Honesty, as well as honour, forbids us to take advantage of our neighbour's liberality, and to impose, upon those who give freely.
