Hebrews 11:9
By [having] faith, he became an alien in the foreign country that had been promised to him. He lived in tents, along with Isaac [his son] and Jacob [his grandson], who [also] were to receive the same inheritance he had been promised.
Hebrews 6:17
Since God wanted to show conclusively to those who would inherit the promise [i.e., Abraham and all of his spiritual descendants], how unchangeable His purpose was, He confirmed it with an oath.
Acts 7:5-6
But God gave him no inheritance [here at that time], no, not even a place [of his own] to stand on. Yet God promised that He would [someday] give it to him and to his descendants after him [i.e., the Israelites], as a [permanent] possession, even though [at that time] he had no child yet.
