Rashi Studies (Advanced)

G‑d promised Avraham not only that his children would own the Land of Israel on a national level, but that each one of his descendants would privately own a piece of the Land. This can help us understand Avraham's negotiations with the people of Cheis.

Why did Avraham not allow Yitzchak to leave the land of Cana'an? And if the land of Cana'an was so special, why was he not allowed to marry a girl from there?

Could it be that Hagar, who lived in Avraham's home for so many years, turned to idol worship? We must conclude that she did teshuvah afterwards and made her reappearance as Keturah.
