And after this, Abraham buried Sarah his wife in the cave of the field of Machpelah (Gen. 23:19)
Till today, Ishmael's descendants claim that the Cave of Machpelah (in Hebron) belongs to them, by virtue of their being the children of Abraham. Among the rejoinders: 1) Ishmael did not have the right of inheritance, as he was the son of a maidservant and not Abraham's wife. 2) Ishmael had no connection to Sarah, so obviously he has no entitlement to a property that was bought as her burial place. 3) In the modern era, the majority of Arabs living in the Middle East are not ethnical descendants of Ishmael. (Likutei Sichot)
And Abraham was old, and well advanced in age... (literally "along in days") (Gen. 24:1)
The physical manifestation of day is associated with light and illumination, as it states, "And G-d called the light day." In other words, Abraham's life was completely illuminated, as he did not squander any light of even one day of his existence. (Chidushei HaRim)
...G-d had blessed Abraham in all things. (Gen. 24:1)
There are those righteous people whose main goal in life is to be whole and one with G-d. But this is not the way of the true tzadik. Indeed, the way of Abraham was to concern himself with "all things." He did not worry just about himself, but about others as well. And so he was blessed in a like manner. (Rabbi Levi Yitzchak of Berdichev)
