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.
Acts 7:5
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.
Hebrews 11:12
Therefore, from one man [Abraham], who was as good as dead [i.e., because of having a sterile wife], were born descendants as numerous as the stars in the sky and as countless as the [grains of] sand on the seashore.
