Adam Clarke's Commentary on the Bible - Hebrews 11:9
By faith he sojourned in the land of promise - It is remarkable that Abraham did not acquire any right in Canaan, except that of a burying place; nor did he build any house in it; his faith showed him that it was only a type and pledge of a better country, and he kept that better country continually in view: he, with Isaac and Jacob, who were heirs of the same promise, were contented to dwell in tents, without any fixed habitation. read more
