Isaiah 51:2

51:2 Look at Abraham, your father,

and Sarah, who gave you birth.

When I summoned him, he was a lone individual,

but I blessed him and gave him numerous descendants.

Acts 7:5

7:5 He did not give any of it to him for an inheritance, not even a foot of ground, yet God promised to give it to him as his possession, and to his descendants after him, even though Abraham as yet had no child.
