And Sarah died in Kirjatharba; the same is Hebron in the land of Canaan: and Abraham came to mourn for Sarah, and to weep for her.

Wesley's Notes

23:2 Abraham came to mourn for Sarah and to weep - He did not only perform the ceremonies of mourning according to the custom of those times, but did sincerely lament the great loss he had, and gave proof of the constancy of his affection. Therefore these two words are used, he came both to mourn and to weep.

Jamieson-Fausset-Brown Bible Commentary

2. Abraham came to mourn for Sarah, &c.-He came from his own tent to take his station at the door of Sarah's. The "mourning" describes his conformity to the customary usage of sitting on the ground for a time; while the "weeping" indicates the natural outburst of his sorrow.

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.
